Is West Systems epoxy, or regular resin, with weighting, a good fix?

Epoxy is great for making fiberglass repairs, but I'm not sure what it
is that you want to do.

No! Having done epoxy work on this boat, I have found from experience
that the epoxy eventually debonds.

If that's the case, you're doing something wrong. Epoxy bonds to
polyester resin with FAR greater strength than polyester resin bonds to
polyester resin. All that's necessary to get a good epoxy bond is to
clean and sand the surface thoroughly.

What are advised cements/glues/caulks for these purposes?

3m 5200.

While 5200 certainly works, it's messy to work with, a nightmare to
clean up afterward and it takes several days to cure. Lexel and GOOP are
much more "user friendly" and bond just as well. Lexel is used by many
kayak manufacturers for bulkhead bonding. I don't know of any companies
that use 5200.
