Crystal clear after wetout with varnish or another layer of epoxy.

: My only experience with fiberglass is small repair on some sailboats where it
: was to be painted later, and clarity wasn't an issue. What I am wondering
: is what does it look like after sanding the fiberglass to remove bumps or
: high spots? Even with a fine grit, is it still crystal clear? Do you have
: to paint on some epoxy after sanding to make it clear again? Or does the
: varnish fill any fine scratches to make it clear?
