Hi!
I will be sending my 68 912 to have the under side, engine bay, trunk, and interior floor media blasted soon. They have offered to apply my paint of choice as well.

I plan on using some kind of body shultz in the engine bay, underside of the car and trunk but maybe not on the interior floor?...anyway my question is should I have them prime those areas before I apply the shultz or should I try to get them to apply the shultz directly to the bare metal?

Any advise would be great!
