It was suggested I post this over here with you model making folks. I'm using Alumalite Performance 65D and Amazing Clear cast. I'm working on to reproduce some plastic parts. These are thin 1/16 inch translucent parts. I'm helping to make a custom dome light lens. I've already created the mold and attempted to cast 15 or so parts. I'm either using the wrong chemicals or something in my process is wrong. The chemicals aren't cheap. I'm using a vacuum chamber for my chemicals, I'm hoping someone here is a hobbyist doing some of this stuff. If you're actively into this stuff and can help me out, please PM me. I'll send you my number and we can talk. Thanks Craig
