I've put 2 coats of epoxy on the deck of my boat(no fiberglass) and am sanding the epoxy in prep for varnishing. I've sanded to a generally dull finish but have little "freckles" of shiny epoxy e.g. tiny low spots in the finish in several areas. Will the varnish cover these spots with an even clear colour? If I try to get all the spots out I'm afraid of sanding into the bare wood. Also, I have a similar situation on my fiberglass hull where I'm preping for a solid colour polyurethane. Am I right in assuming that the urethane will fill the depressions if they are very small and random? As in, almost imperceptible (The weave is sanded flat)
