Interior refit 1970's kit sailboat questions

[Spot]

Working on the interior of a 70's owner-assembled sailboat.

Previous owner filled berths with EPS (Styrofoam) and glassed tops to hull.
Mice chewed and pooped aplenty before I bought the boat.
I tore everything out including cutting 32 feet of 3" tape on the hull to berth seams and now am beginning the 'fables of the reconstruction'

I rebuilt the side berths with hatches and planning to glass and screw them same as PO did before. I have resigned myself that my work will be 'functional' but not 'pretty' , just trying to get it in water for use rather than a brass and hardwood type renovation. I have some questions to ask that more or less indicate whether I can get materials at a big-box store or need to make a field trip to a chandler's or a composites supplier.:

1. 40+ year old Polyester resin GRP boat. OK to use 3" FG tape and more PE resin to attach tops to hull? Better to use vinylester or epoxy as a repair resin?

2. OK to use an exterior rated construction adhesive to prevent resin drain at hull/berth joint and to help adhere berth to red framing members of boat?

3. OK to use a waterborne enamel (durable exterior, porch type paint) to paint seating areas?

Trying not to overdo or underdo needed repairs.

Thanks for the input!
