Oven cleaner doesn't work with paint/powdercoat, only anodize. Just use paint stripper and sandpaper and then use some fine sandpaper at the end to give it a good finish, also for a good finish only sand in the one direction.
airplane paint remover or gasket remover makes powder coat bubble and come off with just a puddy knife or screw driver, you can get em at any auto parts store.
Not true. The paintstripper method is wayyy easier and less time consuming. Literally its like spraypaint. Spray it on, go do something else for 5 minutes, come back and then it should be all bubbled up and cracked and very easy to scrape off
What works really good after you use paint stripper that I did with my DH frame, was use a pressure washer after so you don't burn your hands getting it off, Sprays right off.
