After hearing everyone sing the praises of Evap-o-Rust for years I decided today to give it a try. Well, I was thoroughly unimpressed. I decided to start with a rusty drill bit gauge and see how it worked. After soaking 3-4 hours I pulled it from the bath of EOR and the whole damned thing is black! It looked like I cold blued it!
I put it back in its bath and I will see what it looks like tomorrow. I expect it to look through same. I plan to wire wheel the crap out of it and see if that helps, but I don't have high hopes.
Fortunately, I already have several so tossing this one won't be any real loss. Originally I intended to follow that with a couple of V Blocks and a couple of small machinist squares, but after that, no way will I chance that so I will do what I have done for over 40 years, wire wheel on the bench grinder.
It will be a long time before I try that crap again. I am so glad I only bought a Qt and not a gallon!
I guess I should not be surprised, through my life I have found the majority of things that work so well for others always seem to work the exact opposite for me. 😄
