The #*!(@#) who painted the passenger door on my "all original" 68 screwed up and painted the interior the same color as the exterior. The genius also slathered bondo over the grain (thick too). I have pulled the panel, masked that sucker off, stripped it (that aircraft stripper is something else-- but it even takes work on Bondo) and revealed a beautiful, pristine grained door panel. While I'm at it, I'm replacing the window felts, hardware and regulator -- but my question is -- to paint the interior side of the door and keep the grain (I'm spraycanning it) how much and what kind of primer do you recommend -- or should I dispense with primer and go straight to color. I can't believe the "painter" committed this atrocity -- and don't want to commit one myself.
