: Over the past weekend (Friday) I saturated the hull of a S&G (Standard
: Ospry)with epoxy, then (Saturday) laminated on the fiberglass, then
: (Sunday) laminated a thin strip of fiberglass along the keel plus put on a
: sealer coat of epoxy on the hull - squeeging after each coat. And (Monday)
: just finished scrapping off the epoxy bumps and drip lines.

: Should I do anything else now with sanding or epoxy? Or just wait until after
: the rest of the boat is built, since the varnish coats will give it the
: gloss?

Three coats is usually the point ot check your work. Very thick resins may do the job in two, and very thin resins may need 4 or 5 very thin coats.

If you still see the weave pattern of the fiberglass cloth, then put on another coat of resin. If that doesn't "kill" the weave, then probably the resin is "telegraphing" the weave by coating the underlying layers with a very even coat on the highest spots, and not just settling into the valleys. Let it sit until you go to varnish. By then the resin should be nice and hard and a light sanding will knock off the excess resin on those tiny high spots, withtout removing so much that you sand into the well-coated cloth itself.

Hope this helps
