Anybody used this stuff? I just got my first supply a week ago and have finished processing the first group of things, and so for I'm impressed. Great way to save old tools and keep newer tools looking good, to refurbish old bolts and other parts instead of buying new ones, and to totally strip items of rust before painting.
Only caveats so far: (1) longer soaking times that directions imply - they say 24 hours will handle toughest jobs, but I've had some pieces take up to 3-4 days, (2) a few items rerust very fast (within 3 hours) after treatment, but not if promptly treated with a rust-preventive agent - not sure what made the items so prone to rust (iron bar and set of files), (3) I don't think it does so well on stuff that's too big or too attached to be soaked - I am starting a job today to test this, where I plan to repeatedly wipe it with the stuff and let it pool on the surface top.
A couple related questions have occurred to me, too, if anybody knows the answers: (1) what chemical process is at work here? (2) is there a cheaper substance that does the same thing - this stuff costs around $20/gal (3) for items to be painted, I'm still using a rust converter as the base coat even where there is absolutely no (visible) rust left - is that wrong?
