Back when I was a kid in like 1980 the guy I worked for had a C-114 tractor 290 cummins, 15 speed deep reduction. It was early 70's so it wasn't that old, but it was all primer spots and had a hole in the left fender about the size of your fist. Nobody wanted to drive it. One older guy "Marvin" who occasionally suffered from something he called "wine cramps" used to drive it real local loading trailers and bringing them back to the yard.
So one weekend, I fixed the hole in the fender, sanded and primed it, then wet sanded it, and shot it in Mack Standard Red with some of that Kirker paint that mack sold for like 25 bucks a gallon. I'm no great painter, but the stars must have aligned or something and it came out beautiful. Then everybody wanted it, but no way was Marvin giving it up. He called it "My Pretty Red Truck" and actually started washing it, waxing it, and polishing the chrome
