The blast shop I brought my project to did a great job of completely blasting the body/chassis and other parts to remove all the old paint and surface rust, but then they shot DuPont Variprime 615 2-part etch primer over everything. I know I need to remove the etch primer in areas I want to add filler, but can I apply a primer/sealer over the etch primer and then apply chassis black over that?
Or do I need to have the Variprime etch primer completely blasted back off and then go with the chassis black primer and chassis black? I understand that it is not recommended to shoot chassis black directly over the etch primer, but is it OK to prime/seal over the etch primer and then apply chassis black?
On the body I was going to shoot a primer/sealer and then topcoat. Seems like that is the guidance from DuPont literature. Even looks like you can shoot a DuPont epoxy-based primer/sealer over the Variprime, which is probably the way I’ll go.
