Eastwood, Extreme Chassis Black (Satin) has a close sheen to OEM. Shoot the rear axle as well with it. It's epoxy based (premixed), so the durability is there. I believe you can spray it on bare metal or self etching primer. I personally would prime it with a self etching (high zinc) then spray the Eastwood over it.
For my mustang (unibody), I'm blasting it - spraying self-etching primer, and then going with PPG-DPLF epoxy primer for the body (blue) then topcoat.
Which topcoat will you apply over the DPLF?
