I am planning to clear coat my first playfield myself, Using 2 part Auto clear coat. I was thinking of doing a coat, let it dry briefly and hitting it again, then wet sanding and hitting it with a final coat and wet sanding. Should I mix it for the first 2 coats separately or will it keep until the first coat hardens
and then shoot it again. Also how much should I mix for 1 coat as I don't want to make to much but still want to have enough to get a good coat on it.
