Re: need help!1976 procraft bass boat
There are as many ways as there are members of this forum. And we all have our own opinions and bias..
Personally in my project, link is in my signature, I followed Jim Anderson's recommendations and DID NOT seal the bottom of my floor.
Read Jim's book - Runabout Renovation: How to Find and Fix Up an Old Fiberglass Speedboat by Jim Anderson

I also opted to use Polyester (fiberglass) resin because it is less expensive and if it held up from 1960 until today that means my repair should last until about 2040.
The main thing to remember if you try to use both Epoxy and Polyester resin, is that you can NOT apply polyester resin over top of Epoxy, it simply will not set up. You can apply epoxy over polyester, but not the other way around.
So don't try the idea of using epoxy putty for the edges of the floor and then think you can glass over the floor with Polyester resin, because the resin over top of the epoxy putty won't set up.
As for materials, get a GOOD FRESH supplier for resins:

And there are some great deals on scrap cloth, etc that were ends of rolls on eBay:

One finaly note, if you do go the route of sealing both sides of the floor, remember that polyester by itself, with out mat or clothe will not stay on wood:
