Hi,

I am planning on making some car panel moulds, can you tell me if I can make the mould from panels in primer or do they need to be painted?

Thanks

Been looking into this recently and do not recommend fill in any way as it comes out of the part and sticks to the mould, can be cleaned off but adds work.

regards 2K primer I think it works well so long as its cured, ive theory that it needs post curing as such that unless its old you need to cure it to above the temperature that the tooling gel coat gets to when curing, you get a load of heat in the resin and if your paint has not been above this you get can then get problems.
