I went looking for some of that at Canuc Tire and they were out so I tried a product Enviro Rust on a handful of bolts. Now I forgot them and they sat all night and they came out a black oxide finish so I'm not sure if that's from being in too long but the rust was gone. I want to give that Evapo Rust a try it looks impressive. Thanks for showing us your results.
