I agree 100%. Over the years I repaired several polyester boats with
polyester. Cleaned with acetone and washed down. Feathered the edges and
sanded as recommended and carefully laid the glass. EVERY one of them
started peeling within a few months. Five years ago I changed to epoxy.
Not a single failure of any kinde ever since.

My old Nautilus 8 Dinghy was damaged by Ivan and has a sizeable hole
in the side. I have some polyester resin on hand and I am wondering
if I can use it instead of expensive epoxy for a repair. Other than
some sanding, how do I prepare the surface to make sure the resin
adheres. The dinghy is at least 25 yrs old so is very weathered.

HAving repaired more than a few I would make note of the fact that ALL
sources say polyester to polyester is not recommended. Use Epoxy for all
repairs of polyester. PERIOD!
