I am rearranging a couple winches on the coach roof on either side of the companionway. Some of the old holes will be exposed in a fairly visible location. I am thinking of filling the holes 90% with thickened epoxy, then after it cures putting in a dab of one-part white Gel Coat Scratch Patch. Will this look reasonably OK or do I need to go to a more elaborate repair?

Thanks,
Max
