Stripping paint/rust from body

[Rsconv68]

Whatever method you use, mask off those markings and you can hand apply whatever method you use on the rest of the car.

They used a plastic media on my Camaro. You could see all the crayon marks on the firewall. I didn't redo them, I documented them with pictures as it was getting painted over again. You may have to sand blast in the areas where it's rusted. Start with the media unless somebody has another way. They have special tape to put over the Fisher body tag. Don't remove it...Joe

It would be nice to know what part of the country you're in to know what to suggest for a local source.
There are places that do total immersion in non-toxic solutions that remove everything but clean steel and that is all you're left with. The one I use is near Milwaukee, WI and he does pieces to whole body and can have the entire body dipped in EDP after too. The EDP his partner uses is better than what is on the NOS parts I've bought. My, lifetime, bodyman/painter that is helping me was so impressed, he is now taking all this restoration parts there too.

Any total dip in solution is, most likely, going to remove any chalk marks and even stripping by hand will need great care to avoid the marks.
