Marine Tex Repairs
Well, it depends on how extensive the damage is. The small repair that I did in the cockpit was a bit smaller than the size of the fingernail on your small finger and about 1/4-inch deep; and it was on the side edge near the access hatch-starboard side. Marine Tex is fairly easy to work with, just mix per instructions (a few drops of hardener to a small amount of putty), mix up using a putty knife or stick, then fill in the hole. Over-fill the hole and after cure you'll wet-sand it down (with wet sandpaper and a wood block backing) to match surrounding area--it sands fairly easy. If the color match is good (in my case it was), then polish with rubbing compound, then wax. If it's not a good match, then you can touch up with gel-coat over the Marine Tex. If in doubt, mix up a small amount and try it on a piece of wood with a hole in it (2x4 with 3/4" hole) to get some experience with it. It's not that expensive and it's not that hard to work with and it's been around for years.Otherwise, locate a local fiberglass repair guy and have him do the job. In my harbor there are several that do great work to where you can't tell where the damage was. It just all depends on how much damage was done.Hope this helps and good luck (and hope your friendship didn't get lost with this hit!-good friends are hard to come by, even if they do make mistakes!),Gary
