I’ll skip the back story but I acquired a few moulds but the surface finish on some of them is not very good. Scratches, wavyness, bumps on the plug which are dents on the mould, etc. I’ve done body work for about 11 years so filling and sanding the surface smooth is not an issue. My plan was to sand the whole thing smooth, prime with an automotive 2K primer, sand that smooth, then several coats of automotive clear coat, buff and polish. The original tooling gel coat has been, or is really close to being sanded through, and some of the blems are pretty bad which is why I figure recoating the surface is my better option. Any input would be appreciated.
Is your mould polyester or epoxy
Is your product polyester or epoxy
How many parts would you like to make during the rest of the life of the mould
How is the rest of the mould? Reinforcements, back structure, etc. Water damage? Spider cracks?
Is the material of the mould suitable for your production plan (primarily temperatures reached
Not to discourage you, in contrary, but this is needed for a founded advise. It can be done, it can be good, but there are other options.
