Polyester is easier to work with, especially for amateurs. Just make sure you've got a wide enough area to bond.
And that Petit rep was trying to sell you something. And is flat-out wrong.

The Sunfish are made with polyester resin. Old School. It is cheaper than epoxy resin, New School. Epoxy bonds to poly but not as well the other way poly to epoxy. Boat pros I have talked to recommend epoxy for REPAIRS, and Polyester for BUILDS. One rep from Pettit told me that some insurance companies would only cover the repair?if it was done with epoxy.
Talk amongst yourselves...

When grinding and laying up a cloth patch, that's not necessary. I
prefer to keep the hull to one family of resin to make future
repairs easier.

any other ideas on getting smaller quantities I’d be much obliged.

specifically for your recs for thickened epoxy. But it turns out I
have a ways to go before I can even get to a leak test to determine
if those traveler holes are even a source.
