Thought I would experiment a little. I Sanded my System Three epoxy down on a S&G recently finished. I then rubed on a very thin coat of Thined epoxy to fill in all the scratches from sanding. Now I wonder how long I should let the thin coat of epoxy cure before I put my Z Spar Flagship varnish on it. I can't find an answer in the System Three Epoxy book, so I thought I would ask here since there is a lot of nice people with a lot of experience here. Has anyone done anything similar? It seems to work and the boat looks good.
