Does it matter if you primer parts

1) How well prepped was the surface and how well is the primer adhered to the parts?
2) What kind of primer did you use ?
3) What kind of mold-release agent are you planning to use?
4) What kind of mold material are you planning to use?
For instance....I had problems making a polyester mold, using a polyvinyl-alcohol release agent over spraycan high-build primer. The mold material attacked the primer through the release agent and stuck to it..... big mess.
I had zero problems with catalyzed polyester primer, polyvinyl-alcohol release agent and a silicone mold material.
I know what works for me repeatedly from years of experimenting, but I don't apparently use the same materials most resin casters do, so I'll leave the 'expert' answers to them.

I think Greg Wann, will most likely cast the parts.
In that case, ask the guy who's going to cast the molds what finish he prefers. I have to specify to my own clients exactly what materials and finishing techniques to use, or I simply can't guarantee my own part of the job.
