Based on the reliable Camaro restoration specialist that I know, one being Larry Christensen when I restored my car, the doors and trunk lid were mounted and aligned on the body prior to paint. I believe this was the typical assembly process for all the GM Fisher Body Plants. So the trunk lid hinge hardware, trunk catch and the two screws (not the latch and latch screws) as well as the door latches were in place when the body was painted final body color. So the three latch screws should be painted. I have many pictures of unrestored survivor Camaro details but unfortunately, not the door latches.
Perhaps JohnZ can share pictures of his car's door latches with us if his car still has its original paint job and no door jam paint work touch up.
Does anyone else have an original paint survivor that can post pictures of their door latches?
I would like to see what, if any, body color overspray you can see just inside of the latch. I hope mine is correct.
