Coating Silazane 50, which is reputed for its powerful effect even for DIY, has the Diamond Series as a higher grade.
The Diamond Grade offers the highest level of protection and performance available in the lineup at Japan.
Even the base grade can be easily applied, but the effectiveness of the coating is comparable to EX Keeper (most popular and flagship coating in japan).
The top grade, Silazane 50 Diamond Plus, offers unparalleled water repellency and durability.
After applying several coatings, we felt that coatings with durability in years are the real thing. Diamond Plus and Diamond 200 are one of the few real coatings that can maintain water repellency even after one year of application.
I also purchased and actually installed Diamond Plus. This review includes the differences from Diamond 200 (which has also been installed).
Silazane 50 Diamond Plus features include
- 3-layer coating with particle density far above Silazane 50
- Water repellency and gloss of the film are on another level.
- After actually installing it, I felt it was definitely more effective than EX Keeper.
I am installing Diamond 200, a layered version of Diamond Plus, though,
Diamond Plus and Diamond 200 have a very high film density and are multi-layer coatings, so the water repellency and gloss are clearly better than one-layer Silazane 50. Water repellency and durability are clearly better than EX Keeper.
The price is on a different level for DIY coatings, but its effectiveness is the best in the industry.

Definitely one of the strongest coatings ever. Silazane 50 Diamond Plus is a highly recommended coating, I would say without discovery.

The difference between Diamond Plus and Diamond 200 is that the ingredients in the third and fourth layers (liquids E, F, G, and H) are slightly changed to make it easier for the third and subsequent layers to adhere.(Diamond 200 is available in Japan)
Diamond 200 has a higher number of films, so the film will be smoother. For more powerful effects, Diamond 200 is recommended.
Construction in hot weather can be done early in the morning & in the shade to avoid mistakes.
The Silazane 50 Diamond Series rarely goes on sale. Don’t miss out on the sale timing.
I once bought one at the regular price because the sale ended early when I was having a hard time finding the right one.

Silazane 50 Diamond Plus Features What makes it different?

What features make the semi-expensive DIY coating different from others?
↓Actual construction. (Open in new tab)
Film density is very different.
First is the film density. This is the first anomaly.
Even Silazane 50, which is 1/5 the price, is a coating agent at the level of specialty store installation,
Diamond Plus is a densely formed film far above that (estimated to be 125 times higher).

It is so dense that dirt and water molecules cannot even be trapped.

Price and actual effect

As I explained earlier, this price is honestly extraordinary for a DIY coating.
But it is more than that.
The effect is certainly better than normal Silazane 50 or EX Keeper.

Since the price differs about 10 times between DIY and store installation, Diamond Plus can be considered as a coating costing about 500,000 yen.

durability

Durability is 3 years. It is no different from the normal Silazane 50, but given this high-density difference, it will last even longer.
The higher the density, the more difficult it is for dirt to penetrate between the particles.
Therefore, durability can be expected to be more than the normal Silazane 50.
However, in order to prolong the life of the coating, basic maintenance such as car washing should be performed on a regular basis.


Disadvantages of Diamond Plus

The downside is the price! What an obvious thing to say on our blog.
Price and effectiveness are proportional. Install the product and be struck by its threat of water repellency.

Note coating compatibility (peeling is OK)
Unfortunately, it may not settle over previous coatings.
However, it can be fixed if it is peeled off using the enclosed ion deposit agent.
In my case, I stripped and installed EX Keeper.
(Silazane 50 cannot be fixed over commercial coatings such as EX Keeper)
This characteristic is summarized in the listing table below.
- EX Keeper or other commercial products + Silazane 50 -> x
- Remove organic layer such as EX Keeper + Silazane 50 -> ○
- Silazane 50 + Silazane 50 Diamond Plus → ○
- Diamond Plus (top coat) + Silazane 50 → x
- Diamond Plus (without topcoat) + Silazane 50 → ○
On the other hand, polySilazanes are compatible with each other, so Diamond Plus can be applied over Silazane 50.

The basic disadvantages and cautions are the same as for the normal Silazane 50. There is nothing special to note because it is Diamond Plus.
Inability to settle over maintenance agents
This is also about compatibility.
There is a maintenance agent for Silazane 50, isn’t there?

Silazane 50 cannot be fixed over these maintenance agents or topcoats.
It is sometimes more cost-effective to apply a top coat of Silazane 50 than to create a sacrificial film with a maintenance agent.
There is also a two-coat version of Diamond Plus.
Diamond 200, a two-coat version of Diamond Plus.

The difference from Diamond Plus is that the ingredients in the third and fourth layers (liquids E, F, G, and H) are slightly changed to make it easier for the third and subsequent layers to adhere.
I have installed Silazane 50 Diamond 200.
I have been telling you for some time that Silazane 50 is the optimal topcoat solution for Silazane 50, but now the officials have admitted that Diamond Plus is the optimal topcoat solution for Diamond Plus.
After all, the goal of the Syrazan 50 is Syrazan Infinite.

The backstage technique to turn Diamond Plus into Diamond 200.
It can be practically diamond 200. That is, five layers of coating.
Here’s how to do it.
For a compact and convertible car like the S660, it is theoretically possible to buy Diamond Plus LL and apply the first layer (liquid A, B), second layer (liquid C, D), liquid A, B, liquid C, D, and topcoat, making a 5-layer coating as with Diamond 200.
The recommended size for Diamond Plus is L for minivan class. M is recommended for minivan class.
An SUV with less uneven surfaces could do well in M.

However, those who wish to eliminate concerns such as insufficient liquid volume should honestly purchase Diamond 200.

Diamond Plus Precautions for Installation
The most important thing is to observe the strict prohibition against water damage.
Others are only “if possible”. The precautions are exactly the same as for Syrazan 50.
- Zero wiping residue after car wash prior to installation (strictly adhered to).
- Water damage is strictly prohibited for 2 hours (strictly enforced).
- Be careful of night dew and other condensation (strictly enforced)
- Construction from dawn (night dew prevention)
- All day sunny day
- Construction in a covered parking lot is preferred.
- Preferably in a garage.
Water damage is strictly forbidden.
As with any coating, pay close attention to the time strictly forbidden to get wet.
Drying time after installation is 2 hours, but this depends on the season and humidity and should be adjusted by the customer.
The curing mechanism of polysilazane-based coatings is that the solvent reacts with moisture in the air to cure.
So, if there is too much excess water, it will fail.
- Car wash before installation
- Construction in progress
- After construction
Water damage is an absolute no-no for these three points.

What is the construction environment that must be strictly adhered to?
There are only two construction environments that must be strictly adhered to
- All day sunny day
- Construction should be performed at dawn (be careful of dew and condensation at night).
As an addition, it would be best if I could avoid dust and pollen, such as a covered environment or garage, but I am not able to do this either.
There are examples in the reviews and word of mouth that fail due to water damage (normal Silazane 50).

Is it OK to construct on a high windy day?
OK.

However, the spray should be applied to the construction cloth, not the body. (The cloth should be dry for installation.)
If you spray it on the body, the half of the car parked next to you, not your own car, will shine with a diamond-plus shine.
This caution is also similar to the normal Silazane 50.

Introducing the Silazane 50 Diamond Plus Review.
As expected, the opinions that the effectiveness of the product is exceptional are outstanding, with basic 5-star reviews.
I also checked the bad reviews and they were about the sale. There are no substantive bad reviews.

Good Reviews
The product is well done without any unevenness in application.
from Rakuten
I used up the entire LL size.
I am convinced by the diamonds that the stain resistance, transparency, and durability are excellent.
I am looking forward to seeing the slippery feeling after it is fully cured.
Although I have not yet confirmed the effectiveness of the product, I have the impression that it will be effective as I have already experienced Silazane 50 Diamond.
Here are some reviews from Diamonds Plus as well as Diamonds.
It was very easy to apply, and I could feel that the gloss of the body was clearly improved.
from Rakuten
I look forward to washing my car because it repels water very well.
If there is a little dirt on the body, the dirt is removed when I run in the rain. It is so much fun to watch the rain sliding off the body.
We had it applied to our new car.
from Rakuten
I was not sure whether to go to a dealer or a well-known coating specialist, but I was concerned about the cost performance and the reputation on the Internet, so I decided to purchase it.
The finish really reflects the scenery on the body like a mirror.
It is one of the best.
Ease of application, effectiveness, and gloss of the coating are all great, according to many reviews.
Zeus Clear’s spray type Silazane 50 system has a very short installation time.
The installation itself takes 30 minutes for normal Silazane 50 and 1 hour for Diamond Plus.
Very easy to coat.

Bad Reviews
There are 0 bad reviews regarding the quality of the coating.
Only one review was received, which was as follows
I bought it before the campaign and wanted to buy it if I could get it at a discount.
Our blog will also show you the cheapest way to buy the product, so you can solve this problem when you open this article.
This is probably because only car enthusiasts and car chemical enthusiasts are willing to apply such expensive coatings.
If your budget is OK, the Silazane 50 Diamond Plus is a highly recommended product.

Diamond Plus Contents

Contents Introduction.
What a surprise, this Diamond Plus is a three-layer coating.
- The first layer is A+B + curing accelerator
- Second layer is C+D+cure accelerator
- Top coat on the third layer
There are of course 3 sprays and a set of 10 cloths.
Not enough! It is indeed Zeus Clear that there is no such thing.
It is an ideal coating content, as it is not stingy and can be used with bang-for-buck tools.

Diamond Plus installation procedure

Diamond Plus is a very high-end coating, so be thorough.
It takes more steps and more time than the normal Silazane 50.
It is especially hard to get to the groundwork.
If you divide the car wash into two days, do the first day up to the wash to remove the ion deposit agent, and on the second day, start with the special shampoo.
car wash | Commercial car shampoo | 30 min. |
getting rid of something (e.g. dust in the wind) | Lightly is OK | 15 min. |
Surface Preparation | Ion Deposit Agents | 30 min. |
car wash | Special shampoo included | 30 min. |
getting rid of something (e.g. dust in the wind) | Thoroughly. | 30 min. |
removal of fat | Special degreaser | 15 min. |
1st layer | A + B + curing accelerator | 30 min. |
2nd layer | C + D + Curing accelerator | 30 min. |
dryness | – | 2 hours |
3rd layer | topcoat | 30 min. |
However, it is to immense effect.
It will takeapproximately6 hours.Let’s get into it.

First, wash the car

First and foremost is the car wash. Do not use the degreasing shampoo that comes with the shampoo before ion deposition.
First, wash the car normally. It should not contain compounds, waxes, or other strange substances.

Remove dirt, including mud, thoroughly.
Next, we will use an ion-deposit agent, so wiping up is only necessary to reduce the amount of water.
Reset substrate with ion-deposit agent
Ion deposit agent is used to reset water stains and coatings.
If the coating is coated with an organic film, in particular, use an ion-deposit agent to remove it thoroughly.
Wet the cloth with water and apply the deposit agent.
It can be removed by wiping lightly many times without rubbing hard.

Included with Diamond Plus.
Car wash with degreaser
Wash the car with the supplied degreaser.
Up to this point, the groundwork has been made.
If you want to prepare the surface with a polisher, there are more steps, but it is still the same process of degreasing and applying Diamond Plus.

Wipe down thoroughly (to avoid failure)
Next, wipe thoroughly.
Moisture is a parent’s enemy.
Let’s do it with this spirit. We will eradicate the water droplets.
Blowers are very useful here. It is very convenient to have it.
I would recommend a Makita 40V, but an 18V will also work.


Special degreaser is applied
After washing the car, apply the degreaser provided.
Lightly blend the cloth and apply.
Apply Diamond Plus to the entire surface of the body to be treated.
Construction from 1 to 2 layers

After degreasing is completed, the installation is done immediately.
Polysilazane coatings generate ammonia when they cure in a chemical reaction, so wear a mask, safety glasses, gloves, etc.
Liquids A, BC, and D cannot be stored after opening. They should be used up. (Can be refrigerated for 1 year if unopened)
The procedure is simple: put Liquid A, Liquid B, and the effect accelerator into the spray bottle in that order, and shake to mix.

It is then sprayed directly onto the body or sprayed onto a cloth for application.

Personally, I recommend spraying the crosses for wind protection.
Two to three pushes apply about a 50 cm square.
The second layer is applied using the same procedure.
It is OK not to open the space between the first and second layers, as long as the second layer is not immediately after the first layer is applied.

The third layer (topcoat) is applied after 2 hours.
The third layer is applied after 2 hours after the second layer; it is OK if applied within a week.
The approximate diamond base can be done up to the second layer, so the touch of the cloth during installation is different.
The cross slides down the street without doing anything! It’s like.

Finished by drying for 2 hours after top coat.
After the topcoat is applied, it is allowed to dry for another 2 hours to complete the strongest coating.
Compared to the normal Silazane 50, it requires twice the installation time, but the effect is even more extraordinary.
It takes about 6 hours from car wash to completion of topcoat application.
The wash and dry time is very long, and the installation itself is quick. Be patient and wait for it to dry.

How to buy Diamond Plus at the lowest price
The official sale discount rate exceeds Amazon’s large sale discounts (including point redemption).
Sale and coupon code information is organized in the article below.
The sale is also updated regularly, so be sure to check back.
In addition, you can use your Amazon points as payment for the official product, making it the most economical way to buy one.

Maintenance of Diamond Plus
The topcoat can be protected byusing a special maintenance agent.
The maintenance agent is a separate component from the topcoat and is treated as a sacrificial film of the topcoat.
To use, spray on a cloth and apply to the body after washing – wiping off the car.

It should be applied in a span of six months to a year. The capacity is about 2 times and should be stored in a cool, dark place.
summary

In this article, we summarize the Silazane 50 Diamond Plus, which is arguably the strongest coating available at this time.
I am installing its layered type Diamond 200, and its effectiveness and durability are truly amazing.
Definitely a coating that you will not regret purchasing.

The following points should be considered when applying the coating
As long as you adhere to the strict prohibition of water damage, you seriously won’t fail.
- Be very careful about water damage.
- All day sunny day
- Construction in a covered parking lot is preferred.
- Construction from dawn
- Water exposure strictly prohibited for 2 hours (depending on season and humidity)
- Beware of night dew and other condensation
Also, use the enclosed ion deposit agent, as it cannot be coated over an organic topcoat (it is difficult to fix).
