One of my recent favorite YouTube channels is Carter Auto Restyling:
https://www.youtube.com/@CarterAutoRestyling It's a young fellow in Canada who does some pretty impressive auto body work - rust repair, fabrication, dents, metal finishing. He has a quirky sense of humor and mainly works on Advanced Design (1947-1953) Chevy pickups that are by most standards way too far gone to even consider saving, but when he's done with a repair it looks better than new. Pretty educational to see what can be done in a home garage with a minimum of tools.
