: There is a void that extends forward and aft of the hole, making it
: impossible to sand smooth the sharp edges without enlarging the
: hole, because there is just a paper thin layer of gel coat, then
: air, then the fiberglass mat they used to lay up the deck. In
: any case, I won't get to it until it stops raining, so that'll
: give more people a chance to weigh in. Must be a slow news
The gel coat serves no structural purpose. Sand away until all the void is gone. If you want it pretty take get a small bottle of Testor's Paint.
