I was wondering if anybody could give me some advice on US Composite's epoxy for my Wildman Punisher 3 build. Mainly, I just want to know which resin and hardener I should get for fin fillets. The medium hardener seems to be the one recommended by US Composites, but then should I use the thick or thin reason. Will this combination be heat resistant enough for the fillets on the mmt? Additionally, should I add some chopped fiberglass to my fillets?
