I am very familiar with those old trucks and the small panels that make up the cab, held by rivets instead of welding. For those who don't know, they made the cabs out of aluminum sheet and just overlapped them and riveted, just like they build trailers, some areas would have small bulges. The doors may only have rivits on the perimeter, but the cab has rivets everywhere. I toured the factory in Nashville around 1974, and was very surprized with their assembly and paint process. As I remember, they built the cab right on the assembly line Piece by piece, even the doors, then it went to the paint booth. During the 70s the Peterbuilts had a lot of pin stripping, and they had people laying out the lines with tape, just like in a custom paint shop. They were building about 20 trucks a day at that plant. And the odd thing was that they ran the cab back through the booth for every color. No masking, the first color would be what the cab had the least of, then they would tape over that, run it through again, and tape over that color, and keep doing that with all the colors. No sanding and no buffing, they used mostly Imron.
Moose, you will have a hard time buffing that, with all those rivets heads. And the rivets are sitting on top of a second panel as you are buffing up to them. I would think a lot of rivets and maybe panel edges at the seams will have burn throughs.
