Not a C10, but here's my 1963 Turd Bird. It took 56 years to develop this original patina, so I'm not gonna paint over it. The first pic is after buffing it some and polishing the glass. The second pic shows how I found the car vs. the progress on half of the car after scrubbing with comet and scotchbrite to remove the funk. I plan to buff and wax one more time, reinstall all of the trim, and drive it as is.
