Ok, so I know some folks thought I was nutts, saying my survivor paint black 69 L78 has a black painted tail that is a different paint than the body.
So I went and checked the black survivor paint 1969 427 baldwin motion camaro at the muscle car nationals this weekend (a car converted from a L78), and it was like looking at the same car as mine.
The paint masking marks that run at a 45 degree angle inside the trunk opening area were clearer on that car than mine. There were other details around the tail lights that indicated there were 2 different paints used. I showed it to the original owner of the car, and his nephew (who owns it now), and they agreed 100% with me that it was painted, and their words were it was a different duller black than the body paint.
What was also interesting, was the sheer amount of orange peal on the bulk of the tail panel on the flat surface between the tail lights. It was EXACTLY the same as on my car. Both our cars have non orange peal trunk lids, D80 spoilers, but the tail panels look really different in terms of paint texture (rivers of orange peal, no drips though).
The car's VIN is in the 600K range, mine is in the 656K range, so they are a fair amount apart to say this did not just happen in one week of production. Both are Norwood cars.
The car has the same red hockey stripe paint and sticker attributes as my car too. The stencil used for the painted stripe left behind small tic marks ever inch or so, and that was neat to see (only some original paint cars will show this).
I think it would be of reasonable consideration to now say black ss 396 cars got their tail panels painted following the standard process.
