Re: rivet holes
I filled in several hundred holes on my 20' sf. What I did was 1)reem out hole with drill bit 2)use countersink bit to smooth out outer surface and to give the epoxy a little more surface area to bite to 3)back inner surface with duck tape 4)fill holes with thickened epoxy 5)remove duck tape after epoxy cured. This worked pretty good but was a major pain in the ass due to all the holes. There must have been 3 or 4 different rub rails installed over the last 30 years.
