I'm sanding the top edge of the hull in prep for the deck glassing (want to avoid burying runs/bumps/etc. under yet another layer of glass/epoxy). I noticed to get rid of all the ripples (read "runs") I had to sand to the point that the glass pattern became visible. Is this too deep? I was thinking I could sand everything to this level (nice and level) and then apply a couple more very thin coats of epoxy to build the finish back up.
Any suggestions? I don't want to go too deep into the glass but do want to get a smooth finish for varnish/poly.
Thanks in advance,
