Hi

I am currently building a Datsun 240Z and wanted to make some of the parts from carbon fibre. The body shop repaired all of the body parts, sanded them and primiered them ready to be painted.
This is how it is now. 

So that the mold won't stick to the primer what is the best thing to do? Do I have to paint the parts or atleast clearcoat them?

I am in a similar position to you. I have a matt finished car and I want to take a mold without waxing the matt finish on the plug parts. I was wondering if a very thin stretchy material maybe a bit like cling-film could be applied as a barrier? Anyone know of such a barrier film?
I think the glue on vinyl wrap would be difficult to remove from a matt surface.
