It's one of the brilliant things of pva, it has excellent self levelling properties so it will go flat again once you have picked the bug out. But even if you can't, it's not too hard to sand small imperfections like that out of the mould.

When I did pick them out, it left spots where there weren't any pva. Kept spraying another layer to fill the hole and another bug would fly in a different spot. Guess I should say screw it and gelcoat over the bugs. Finish doesn't need to be perfect since the epoxy needs a uv clear coat sprayed over it so I gotta sand and spray it anyway. Ill give it a shot with the bug son lol....thanks
