Resin for Deck and interior work

Lancer 28 Port Lavaca
Howdy!
I've gutted the interior of my sailboat and It's almost ready to paint. Before we paint we are reinforcing the bulkhead under the mast (there no signs of compression yet), next we are closing up the bottom half of the companionway, and right before painting we are going to apply a resin over the fiberglass to hide the honeycomb look.

A few questions.

1. What's the best way to reinforce the athwartship Bulkhead. Our goal is to strengthen the mast without putting a post in (it won't fit).

2. What type of resin do you recommend that will bind to fiberglass, be okay to use for closing up the companionway, and will provide a good base to paint over?

This is for my 1981 Lancer 28. It's in great condition, but it's my first big project and I can use all the advice I can get!
