anybody have any experience with this stuff? Its a phosphoric acid that "converts" rust to black or grayish, hard, insoluble, protective coating. pretty much you spread it over rusted areas that have been grinded down and it helps it from spreading. It also acts as a primer and can be painted over it. I've heard a handful of good things about it.

 

I've used it. It does help prevent the rust from getting worse. But prep is key, you have to get as much of the rust off and what ever is left is treated with the product. You still have to neutralize it with water.

 

i just bought some rust bullet that is sapposed to do the same thing

 

let us know how it works out!

 

i've tried the rustoleom version of "rust convertor" and i guess it works. it is a pain to get "even coats" with it because it's very thin and contains almost no pigments.
