Epoxy or Polyester question

I need to take care of a soft deck core under the bow pulpit mounting flanges. I will be cutting the deck and core using a hole saw, then refilling the hole and touching up with a little paint before re-mounting the pulpit.
1. Epoxy or Polyester?
2. Should I use chopped glass or something else as a filler?
3. Can I fill the hole completely in one shot, or should I layer it in a few steps?
Thanks for any advice.

Why don't you cut a panel off the entire foredeck area and rebuild with epoxy and balsa core so you have greater strength than simply filling a hole? (You may be able to save the skin.)

You may have some problems if the filled hole is supposed to support the bow pulpit in the future: where is the lateral strength from that kind of repair?

I suspect the wet core extends farther out than simply under the flanges. You might as well re-do the entire area.

Epoxy. The only reason to ever use polyester for anything is cost. It is inferior to epoxy in every way but price.

There are lots of different brands of epoxy - Mas, System 3 and many more, some less expensive than West.

Epoxy means not having to re-do the repair in the future.
