I know this is redundant, but I thought I had it figured out. I was going to use PE tooling gelcoat and PE resin/fiberglass for my first mold. Now after making the plug I found out what shrinkage and print through is and am concerned that my mold will be warped and the final part will not fit right.
Should I use PE tooling gelcoat and then epoxy/fiberglass backing? Or am I ok with PE/fiberglass, but I just use a certain method to decrease distortion?
