i had done this back on my duster last summer. not a fun job. i actually haven't worked on the car since because it really tested my convictions to complete the car as well as opened up a whole new can of worms.
after removing all the undercoat, i am now going to have to paint the whole underside of the car. while i have to do that, i decided to paint the engine bay as well since i have the car all apart, why not i figured.
i used the following methods:
- torch and scraper
- chemical peel (some old rust bust from the 60's) and scraper
- younger brother + the above methods
i would recommend using a plastic scraper if possible, as this would eliminate any unintentional gouging of the metal. if you use a metal scraper, file down the corners first.
