The boat I bought last fall has about a hundred little tarp snaps screwed on just above the rub rail all around it. The tarp is probably long gone, and all I want to do is get rid of the snaps. However, if I remove them, then it will leave a hundred little holes in my boat. Is there anything out there like plastic plugs or similar I could plug the holes with? I'm guessing the screw holes are about 1/8" in diameter. I don't want to go to all the work of puting on a new gel-coat. Thanks.
