Why high Solid clear coats? 

As the name suggests, a ‘Clearcoat’ is a non-pigment automotive body finish, meaning you will not see it on your car. But it’s applied over the top layer of your external paint job, thus protecting the underlying paint from damage.

In addition, it provides the vehicle with exceptional hardness and resistance to various chemical and mechanical agents. At the same time, the clear coat will protect the car from scuff and scratches. As a result, you don’t have to redo or touch up the entire paint job when wear & tear occurs. 

Another thing worth mentioning is that clear coats are made of some kind of ‘solids’ and solvents. Consequently, various types of clear coats can be categorized according to the solids’ content in their formula. 

In essence, the solids’ content will determine the topcoat’s thickness after drying. On the same note, this will determine the number of layers you need to apply to accomplish the desired thickness of the topcoat once it dries.

 In that regard, clear coats can be broadly classified into high solids & low solids clear coats. However, in this case, we’ll only be focusing on high solid clear coats.

Generally, high solids clear coats require a few layers to get the desired thickness. As a result, you’ll be using less material, helping you save money in the long term. 

That aside, here are 2 main functions of applying a clear coat to your car; 

1. Protective function 

Applying a clear coat on your car gives it adequate hardness to resist outside elements. This protects it against chemical agents like detergents, oils, and fuels or mechanical agents like scratches, dirt, and bird droppings. A clear coat makes it easy to clean these elements off your car surface. 

Moreover, it provides a strong layer that protects the colored coat from atmospheric agents like UV radiation. Such factors can damage the paint or cause it to fade, this affecting its longevity. 

2. Aesthetic purposes

Another benefit of applying clear coats is that they add shine to your car’s exterior. Besides, clear coats are considered some of the most important parts of a car’s finish. So, apart from protecting your vehicle against external elements, clear coats will determine its physical appearance.  

In addition, the type of high solid clear coat you apply will determine the type of your car finish paint. Luckily, there are various options available including matte finish, satin as well as glossy finish.

Also, you can use them to enhance the visual effects of some colors like pearl or metallic colors, due to their transparent nature.

With that out of our way, let’s look at some high solid clear coats worth buying!

How to Spray High Solids Clear Coat:

High solids clear coat is a transparent layer of paint applied over the base coat to protect it from UV radiation and damage. In addition, it provides a glossy finish that intensifies the color quality of the base coat and makes it easy to buff out scratches. 

Interestingly, applying a clear coat over your car’s basecoat is a relatively simple task. However, before you get to the actual application process, make sure you wear a respirator.

This will protect you from inhaling considerable amounts of paint, which can have adverse effects on your health. Also, wear latex gloves and lint-free clothing. More notably, choose the best high solids clear coat and use masking tape to cover any surface you don’t intend to coat with the paint. 

Next, use 400-600 grit sandpaper to grind down the peeling coat from your car. Doing so will ensure that the surface you’re working on is smooth. As a result, the new layer of clear coat you intend to apply will go on perfectly.

After preparing the surface, hold the spray gun 6-8” away from the surface. Then spray a light coat of high solid clear coat all over the car body.

While doing so, keep the paint wet and thin to shorten the drying time and ensure uniform application. Leave the paint for about 10 minutes to allow it to dry before you apply another coat. 

Once the 1st layer has dried, apply the 2nd coat slowly and carefully to the car body to avoid imperfections and drips. Now, let the paint sit for at least 1 hour to set and cure properly. As part of clear coat maintenance, gently wash and wax the paint regularly to keep it looking fresh! 

Frequently Asked Questions
