Does anyone here know if the fiberglass resins used in the early 70's Boler's were polyester based or were they epoxy based?
Reason I ask is I am building a custom wet bath in ours and the question arose today as if I should use polyester or epoxy resin. I was told the epoxy would bind better to the wood in the wetbath, but would not work with matte as it could delaminate and to use cloth. Several questions were also raised as to the compatibility of primers with the polyester vs epoxy and if one resin would bind to the other existing resin if using two different ones.
Then there was also the question of epoxy paint
vs urethane paint
for the final top coat of the wetbath. Urethane is suppose to have the best UV resisting properties as well as colorfastness. I have considered using the epoxy based primer and paint
for garage floors sold
at the big box stores as epoxy is suppose to bind to just about anything and the garage floor epoxy paint certainly is a lot more cost effective.
Also considered using just a modified alkyd oil based top coat and primer instead of the epoxy or urethane paint/primers.
So many questions and not sure which direction to go with...
