This u wont know until you remove the finnished mold from the panel,
I have made some doors ,
the panels were perfect just coverd in cellulose so i just removed the paint to bare metal and molded from that ,
I then polished the gel coat on the mold surface,
I am dealing with a factory paint finish and so will be celly as its 30 years old. I am not bothered if I cut back to steel but I want to get a nice surface.
Not heard of paint wrinkling before but I am guessing that the heat generated could peel paint potentially in the exo' stage. I will build up the mould over a few days to prevent warp and shrink etc.
