Re: Loon UV thick fly finish
Yes. The second coat isn't "better" than the first, but the second coat wouldnt adhere well to the first coat if it was tack free and smooth. Think of it like painting a smooth object, you want to rough it up with sandpaper before you apply your paint or the paint can just peel off. If you paint glass there is nothing for the paint to adhere to. You can also think of it as a primer.
