At this stage of restoration David
would usually use a self etching primer, but it only comes in
green. In this case we are trying to duplicate what the factory
did, because the primer originally used on this car was black. We
don't understand why the factory did not use a red oxide primer on a red
car, but they
didn't. The only black primer we use on bare metal is epoxy
primer, in this case PPG DP90.
