Choosing the right clear coat can make a big difference. This article will describe what you need to consider before buying a certain product and provide a list of the best clear coats for plastic. We will also suggest what the best clear coat is overall for plastic.

What to Consider When Buying Clear Coats for Plastic

There are a few things to consider when you are buying clear coats for plastic:

  • What a clear coat is and what it does
  • Why you want a clear coat
  • What type of plastic you are painting
  • What kind of clear coat you want

What Is a Clear Coat?

A clear coat is a specific kind of paint that you apply last, on top of the other paint layers. It is a translucent paint that provides a sort of protective coat to the object you are painting. Not every paint job needs a clear coat; single-stage paint jobs do not use this product.

The thickness of clear coats can range depending on the manufacturer. Clear coats can be anywhere from 30 microns to 80 microns in thickness. The thickness will also vary depending on the type of paint job you are doing.

Why Do I Need a Clear Coat?

There are a few different reasons why using a clear coat is a good idea. Let’s take a look at some.

  • Clear coats will increase the thickness of the paint.
  • Clear coats will protect the more expensive paint underneath. A great thing about clear coats is that they are relatively cheap. A lot of regular paint might make a dent in your wallet, so you will want to prevent the paint from wearing out. Clear coats are a cheap way to do this.
  • Clear coats will prevent the base layer of paint from oxidizing. When paint oxidizes, it can become dry, chalky, and ultimately look worn out and cheap. Clear coats will keep your paint looking fresh.
  • Clear coats can change the level of a gloss of your paint. If you want your paint to appear more fresh and glossy, consider using a clear coat. Not only are there glossy clear coats, but there are finishes such as satin and matte.
  • Clear coats will increase the value of your car. If you want to sell your car, or if you know you will eventually sell it, adding a clear coat will be a good idea. It will make any car look new.
  • Clear coats can hide minor scratches. It is quite common for your car to have some small scratches after the base paint job. Using a clear coat can hide the little imperfections.

What Type of Plastic You Are Painting

The type of plastic you are painting might determine the type of clear coat you use and how you apply it to the material. If you are painting a less sturdy plastic that is very flexible, you may want to consider using an adhesion promoter like the Bulldog Adhesion Promoter. The promoter will prevent the plastic from flaking or peeling. You can also add a flex agent that will increase the flexibility of the clear coat.

What Kind of Clear Coat You Want

There are four main types of clear coats that will do different things to the paint job. Let’s take a look.

  • Topcoat clear coat – These clear coats are easy to apply and are quick drying.They are usually applied as the last layer and give a nice glossy finish. You can also polish these coats.
  • Turbo clear coat – People normally use turbo coats for collision repairs. They are great at covering up dents and scratches. Turbo coats are more resistant to moisture and require a bit more polishing to get that beautiful glossy finish.
  • Glamour clear coat – These kinds of coats are good for perfectionists. The coat takes a long time to dry, so you will not have to rush the job. However, you can use heat to speed up the drying process. This coat is also resistant to moisture.
  • High solid clear coat – High solid coats are the most expensive on the market. They take longer to dry and give a thicker layer on top of the base paint.
