Eastwood Rust Converter
Product Review (submitted on June 4, 2012):
Dave is right. It seems there must still be at least a little layer of rust on the entire surface in order to dry, other wise it just stays sticky. Especially if you spray it on too thick. It's like the rust is an "activator". Even then, just do light coats. Frankly, I would just forget this stuff and go right to the "Rust Encapsulator" as you can get it in black, silver and red, and it works more like you expect, like on VW seat spring assembly.
