Rust-Oleum Rust Dissolver, 1 Quart

I have no clue why that one person said it was a waste of money. I have used several different Rust dissolvers or converters over the years. Including the most well known Naval jelly. But this is by far the best thing on the market that I have ever used! I used used this on nuts bolts and washers from a play sat that I disassembled and was going to re-assemble. At first I was going to buy all new hardware which would have been pretty expensive. This was less than $8.00 and work perfectly!
