Clearcoat is one of the most important parts of a quality paint job. From a simple repair to an overall, the final appearance is most notable. In order to maintain a quality finish, the film build of your clearcoat is critical. Film builds that are too high or too low can diminish your hard work.
Dry film builds in the range of 2-2.5 mils are commonly recommended. Too low of a film build (less than 2 mils dry) can lead to reduced durability, premature film failure, dieback, and overall poor appearance. Too high of a film build (greater than 3 mils dry) can lead to solvent pop, dieback, and even potential adhesion failure.
When spraying any clearcoat for the first time, it’s good practice to measure your film builds. This will help you gauge how your application techniques affect final film thickness.
So next time you're getting ready to pull the trigger, remember this tip to produce a finish with long-lasting first impressions.
