i have recently purchased supplies to create my own carbon parts. i have purchased a polyester tooling gelcoat then was advised i should have choosin an epoxy gelcoat. my questions are, can i use the polyester gelcoat to pull epoxy parts? and can i use epoxy and glass fibre to reinforce the polyester mould? if i cant use epoxy glass fibre to reinforce the mould, can i use the polyester tooling gelcoat with glass fibre to reinforce it?

thanks in advance

Just some vinegar to break down the epoxy so you can re-use the brushes and like Carbon Tuner said, acetone.
