I used epoxy thicken with wood flour. The reason I didn't us cabasol is that when it cures, it becomes very hard/brittle. On advice from Beteau.com (shine/etc), I used the wood flour. It would probably work fine either way. I also came back underneath with 2 layers of biaxel 6" glass to cover the filet. It was a little tricky laminating upside down and on an 90 degree, but I was happy with the outcome. I think some of the classic seacraft ride is all the give/slop between the hull, liner, and cap

. That is one part of these boats I don't like. Strick, what do you do to fasten the hull/liner at the rub rail?
Here is a picture of the top of my stringers from underneath.
