Review: Keep surrounding area protected - Very strong solution and works fast.
Review: It WORKS! It literally EATS RUST! - I have used this on a few things that I had already tried several different rust penetrants on with no success, & this just flat-out WORKS! You have to follow the directions! It will tarnish the metal if you leave it on too long & don't wash it down with water as instructed to do. I now have hope that I can get the front brake lines loose on the Dakota I bought that had apparently spent part of its life up North in the rust belt. HOWEVER, I just can't FATHOM WHY they didn't include a BRUSHED CAP! It's a gel that HAS to be applied with a brush, so why not supply it IN the bottle?! That's a glaring oversight in an otherwise GREAT product! I bought some cheap watercolor paint brushes to use for this.
