I molded the epoxy. It came out better than expected. It worked so good I'm going to have to do the rest of the wheel. That nice new epoxy up against the old crappy plastic isn't working for me. If I make the rest of the wheel it will take 2 more moldings. I won't have to worry about cracking at the plastic/epoxy seem. I have spoken with Chuck at PC7 a few times now. He has been very helpful. He said if I mix 1 part epoxy (white) with 1 1/2 hardener (black) it will make a more flexible product. That's what I did. What's the worst that can happen? I do it again? With both wheels, turn signal mech, silicone and epoxy I'm in it for about 80 bucks.
