Guys I need some advice. I bought five litres of Polyester fibreglass resin today ($50 with hardener) as compared to the epoxy resin they had (four litres for $110 with resin).
I can't really find a straight answer about the polyester resin. Apparently it shrinks, is a little brittle, etc.. compared to epoxy.
For modelling or non-structural purposes, is polyester ok? Should I just spend the money and buy epoxy?
Another question is do I need to use gelcoat. The gelcoat that the shop sold was only compatible with the polyester resin and not the epoxy.
