I didn't do the greatest job in the world with the first cut at glassing the hull of my Shearwater Sport.  There are about a dozen and a half fisheyes caused by air bubbles.  Mostly (but not always) where there were holes from the copper wires.  The fisheyes range from a few mm in diam to dime-sized.  I've sanded them down to the wood, keeping the sanded area as small as I could.

My question is, since I'm down to wood in these little spots, does every one need a fiberglass patch, or can I just put a dab of epoxy to level them out.  I haven't filled the weave yet (except in some places where I got the epoxy too thick in the first place). 

Also, where there are 2 and 3 layers of cloth (bottom panels and keel/stern, resp), at the edges the cloth is kind of ragged.  Sand before the fill coats or after?

Thanks!
