Audrey's 1965 Barracuda project
Got all surface rust out from under the dash and inside the roof by mixing phosforic acid with wallpaper glue, let it sit for 3 hrs, then used baking soda to neutralize the acid, and then a high pressure washer, worked well. There is spots that are very hard to reach with normal grinding tools.
