I learned about overcoming a problem painting resin parts. I thought I would post this here. I do some custom resin work for a guy named Mike. He asked me a question that I was absolutely useless to answer. So Mike asked Don the Modelhaus guy and here is what Mike related to me. Hopefully this will be important to you. Mike is a professional model builder and deals with mostly promo cars and is also a body and paint guy on real cars. I personally use the SMOOTH -ON TASK 8 resin. That resin is designed to withstand a good amount of heat.
