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!

Epoxy sticks well to most surfaces but polyester sticks well really only to
polyester, so to my knowledge it is OK to do the repair with the polyester
resin (it is not like you're crossing oceans in this boat!).

Folks like epoxy because it is better than polyester in many ways and a lot
of folks like to 'go up a notch or two' when repairing things.

Personally, I would use the polyester on the dinghy if I had the poly in the
house (and that's from an epoxy salesman!)
