Neil, you are correct about the curing. The product I was exposed to has a small curing process at 140° for about 30-45 minutes. I think the resins have changed this process immensely, and it has been a couple of years since I had someone that was versed helping me. I am assuming technology has changed in that time.

Colin, I probably will only make a small run for our own use on customer's vehicles. The correct size/shape/detailed Battery Cable Support Grommet was never produced exactly in the commercial market and just before Doc Kalinka passed, I purchased about 15-20 from him. I have 2 left, so I want to replicate those. The reproduction Steering Column Anti-Rattle rubber is not correct, and so if i could cast those with the reinforcement cloth imbedded, that would be nice. The same with the Wind Wing Mounting Rubber. Again, just some small one-off production pieces to use inhouse.

Thanks everyone for the thoughts & comments!!
