The roof of Beavis has some deep scratches and surface rust caused by (I think) running the car through the woods under some tree branches. The paint needs to be removed, and I have a couple of methods to test:
1.) Chemical paint stripper, and some elbow grease with a metal scraper.
2.) A ‘flap’ disc attached to an angle grinder
3.) A coating removal disc like the ones from 3M
4.) Palm sander with coarse sand paper
The chemical paint stripper works reasonably well, but there’s a lot of manual work with the scraper, and it’s not a pleasant chemical. The flap disc removes the paint and primer very well, but also scuffs up the metal a bit much and leaves lots of scratches in the surface.
