Re: What is the best way to repair this? PICS
I agree with Snapperbait...just fixed about 4 holes like that in my 40year old Boston Whaler 13'.<br /><br />Grind the area down to the fiberglass about 2 inches away from the hole. (you'll probably find more damage i.e. cracks that go past the hole). <br /><br />I fixed mine according to Boston Whaler.....feathered the fiberglass down from the outside of the entire repair to the hole. Mixed up the resin and fiberglass strands, filled the hole, used a popsicle stick to get the stuff to stick to the backside of the hull and then leveled off. Came back over it with the resin and 6oz cloth. Feathered the edges (sanding). Then I used the kittyhair to fill in the low spots, then used the fairing compound (similar to Bondo) to make smooth. You can't tell there was ever a hole. (actually, my hole was about 3" wide by 18" long)<br /><br />Don't use automotive Bondo as it absorbs water (made with gypsum). West Marine has a great faring compound that works/looks/smells like bondo, but is water resistant. kinda pricy at $18/qt. or you could use this from iBoats

If you feel any low spots or high spots, fix accordingly. The papertowel helps identify these spots. Old veteran car repair guys don't need the papertowel, but it helps the novice.<br /><br />This is from my experience doing bodywork for several years. If you can feel it, you'll definitely see it.<br /><br />Good luck and hope this helps.
