Buyer’s Guide

What is a Clear Coat?

A transparent layer of paint, a clear coat is applied over colored paint. Basically, it is a resin or paint that is colorless. It can make the metal object you are painting shiny making it look brand new again as well as protecting the paint so it will retain that look for a long time.

Other benefits of using it include adding depth to the color and protecting metal objects from UV ray light and the sun that can damage paint or make it fade. It can also help to protect the paint from being damaged by bird droppings, dirt, and rain which can be cleaned and quickly buffed out.

Types of Clear Coats

There are a lot of clear coat options on the market so it is important to know the difference so you can find the best one for your needs:

  • Topcoat – Intended to be the last layer applied to paint, it can be very effective and easy to use giving the paint depth
  • Turbo Coat – This is a fast drying clear coat that gives metal a glossy look.
  • Glamour Coat – A slower drying clear coat, it allows more leveling and is less sensitive to moisture.
  • Higher Solids Coat – Containing more additives, higher solids clear coat has a thicker film after the solvent has evaporated. With its thicker consistency, higher solids clear coats tend to dry slowly and are more expensive than other types.
  • Euro Coats – Euro clear coats dry faster with heat but work just as well as the other types.

Important Facts to Consider

  • Transparency – This is the most important consideration when choosing a clear coat. If you are interested in making the metal you are painting look new again, make sure to purchase a product that does not cover your base paint.
  • Gloss Level – Also important to keep in mind, the gloss level should be more than 90 units so the metal you are painting will look shiny as just as good as a new one.
  • Ease of Application – Since you are only adding another coat, it should not be difficult to apply. Choose an option with a nozzle that lets you spray on the metal’s surface evenly. This will guarantee that you won’t have any blotches on the surface and only a smooth glossy finish.
  • Scratch Resistance – Metal can be vulnerable to scratches so applying another coat will guarantee an additional layer of protection to its surface. Look for a product that has scratch resistance and has UV protection for the most defense against the sun.

Applying Coat

  1. Clean the Surface. Wipe away any paint particles or dust with a damp cloth from the metal’s surface. The surface needs to be cleaned correctly to make sure the clear coat adheres properly and won’t easily peel off.
  2. Apply Clear Coat. Using a paint sprayer or brush, evenly apply the first layer of clear coat. Once it is completely dry, apply a second one which will add another layer of protection helping to keep the coating last longer on the metal. Make sure to wait between 36 and 48 hours before you use your metal object and leave the object in a place where you won’t have to move it to prevent any accidental damage to the finished surface.


It may be a bit confusing choosing the best clear coat for your project, but once you know what to look for, you should easily be able to pick out the best product for what you have planned. Remember, you want good scratch and fade resistance as well as a good amount of transparency for any metal you are working on. Easy application and good protection from chemicals and UV rays are also great features to look for, so make sure to do your research before you head out to the stores.
