I know wood isn't the best choice but for me as a student it was the cheapest way... The finish is good but I'm wondering how I have to finish the moulds before filling them with an epoxy to get the plugs out. I'll finish those plugs once again till a high gloss then. The wooden moulds will only be used once to get the plugs. I have some ideas but wondered what your experiences are with those kind of problems. 1. Coat the mould with a Infusion Resin with a brush a few times. 2. Use vinyl wrapping (carwrapping vinyl to seal everything 3. Use a 2K filler spraycan. and sand till high gloss I would prefer choise 3 but I need to have a confirmation telling me it wont react with epoxy after it... I read it a lot its ok to do it that way but just need the confirmation if possible Matthieu Libeert Founder MAT2 Composites X Sports website: www.mat2composites.com

Sprayable epoxy like Durepox would be the best solution. You'll get high gloss out of the gun as well. Make sure you clean the gun out very thoroughly after putting epoxy through it!
