Interesting. I would have said this clearly shows that the tail panel wasn't full gloss. The front stripe is full gloss - look at the reflection of the camera. Same camera is barely visible in the tail panel shot, and the other reflections are not clear either.

Astute observation.

I posted the two pics together, because I had the same observation.

That's because the front stripe was painted in a different place on the paint line with a different paint altogether and then received additional cosmetic attention between reflow ovens. It was buffed with the front end.

I think the debate has been the percentage of gloss. The tail panel blackout paint is not the same as full gloss used for stripes. The degree of gloss used on tail panels I believe was about 75%. The blackout can be polished and can change to a higher gloss. There are other factors as mentioned. The bottom to me is that there were two distinct paints applied.

I thought the debate was between various survivor cars all presenting with differing shine/gloss on the rear panel?

There is no doubt at all that it was a different paint from the stripes.

DUCO/Magic Mirror was all Lacquer paint.

The Lacquer paint process used by GM required the application of heat to initiate the paint reflow process.

Longer exposure in the ovens or more heat resulted in better reflow characteristics and higher gloss. If the body is already warmer due to ambient temperatures, then a slight gloss adjustment was expected on the final appearance.
