Why is it so important to paint your products in thin coats? I've painted quite a bit and a lot of paints I've use don't require this. What is different about your paints?

Paints that contain a high solids percentage and are moisture cured urethanes (like most of our coatings) require thin, covering coats to prevent the coat you are painting from skinning over trapping the escaping solvents below the skin which looks like micro bubbles on the surface. Most traditional paints are a very high solvents (low solids) content and that is why you can paint those in thicker coats because most of the coat is solvent that will evaporate away.
