Keep the beauty of new and used cars with glass coating!


My car that I decided after thinking a lot.
Everyone wants to keep their beauty forever.
The only way to do this is to wash the car, but cleaning it and keeping it beautiful are a little different.
This time, I investigated the coating that keeps the beauty rather than the car wash.
I hope you enjoy reading it.

About coating

In the first place, a car is made of iron, aluminum, or resin body.
Paints such as white, red, and black are applied (baked) on them.
Car coating is an image of painting the car with more transparent paint.
This transparent coating is called "coating".

Do you need a coating?

When asked "necessary" or "not necessary", it means "it is definitely better to coat".
Because coating can keep your car beautiful for a long time.

The reason is...

Let's think about why it "keeps its beautiful appearance for a long time.
The paint is actually soft
. Of course, you can't see it when you touch it with your fingers, but have you ever touched a thickly painted piece of playground equipment or the "drops" that form when you drip paint on it yourself?
At first glance, it looks smooth and tacky, but it's not
. Even if you apply a thin layer of paint, the paint itself does not harden, so even if it is thin, something soft will remain soft.

Then, when the car is running at high speed, small pieces of pebbles and plastics hit the body.
This allows you to stab soft paint or scrape paint.
This causes the paint on the surface body of the car to deteriorate.
The coating that is applied on top of the paint protects the car from such damage.

Pebbles and pieces of plastic are not the only enemies of paint.
It can also be affected by ultraviolet rays, heat, wind, and rain.
Of course, the coating will protect your car from these as well.

Okay! Let's do the coating!

But first. (before that)

Coatings have great advantages, but there are also different types of coatings.
Let's take a look at the advantages, disadvantages, price, and installation of each.

Oil-based coating

An oil-based coating is a conventional wax.

  • Low price
  • Easy to install even for beginners
  • Less effective in preventing scratches and stains
  • It is not very durable and rain will wash it off, so it needs to be repainted about every month.
  • Stains and unevenness often become apparent as the wax continues to be applied (sometimes the wax needs to be cleaned off)
  • You can do the construction yourself.
Please read the product description carefully without a clear distinction from the glass system

Resin-based coatings

Resin-based coatings are made from polymers (organic compounds) such as silicon, fluorine, and Teflon.

  • A strong film is created on top of the vehicle's paint.
  • The film is expected to protect the paint from soot, oil, and other stains and scratches.
  • It can fill in minor scratches and make the car shiny.
  • It's hard to get dirty, and a simple car wash is enough maintenance.
  • You can do the construction yourself.
  • The effect lasts a little shorter than about 3 months due to factors such as car wash, rain, ultraviolet rays, etc.

Glass-based coatings

A glass-based coating is a type of coating that contains some glass components.


  • It has excellent durability and can be expected to have the effect of preventing deterioration and scratches on the coating.
  • It has a more natural luster and luster than oils and resins, and the effect lasts for about 6 months.
  • You can do the construction yourself.
  • Lasting effect is 6 months to 1 year
  • Relatively easy to install and can be done at a gas station or by yourself.
  • The glass component is "part" of the product, and depending on the product, the content may be too small to achieve the desired effect. (In some cases, even a very small amount of the glass component in a resin-based coating is called "glass-based.

Glass Coating

Glass coatings are mainly composed of glass components such as polysilazane.

  • Much stronger than other coatings.
  • Durability and lifespan are generally said to be "3 to 5 years" (however, since deterioration is caused by UV rays and the effects of the parking environment, deterioration may be accelerated in some cases, and regular maintenance is important to extend the durability and lifespan of the glass coating as much as possible)
  • It is expected to minimize the effects of scratches and various stains caused by pebbles and UV rays.
  • Highly effective at repelling water, so rain stains are unlikely to form.
  • In addition, dirt is easily removed, making it easier to wash the car.
  • The fact that the coating protects against the causes of damage to the car's paintwork means that the car's paintwork will remain in a near-new condition.
  • A clean car with almost no scratches will increase the appraisal value when you sell it.
  • Performed by professional installers, but can be done by yourself.
  • demerit (disadvantages)
  • Basically, it is an expensive process that requires a professional contractor. The lowest price is about 30,000 yen, and the price for two-layer construction with higher strength is 80,000 yen to 140,000 yen or more.
  • If you ask a specialist, you need to leave your car for a minimum of 1 day and a maximum of about 5 days.
Read the reviews carefully and shop convincingly

Notes and supplementary information

If oil or dirt adheres to the coating surface, water repellency will also decrease.
Therefore, it is important to wash the car frequently when it gets dirty as maintenance.
Note! Even if coated, "car wash is necessary!"
However, glass coating does not require waxing, etc.
