    I've had good luck with Evaporust on many projects, but I did leave a pair of channel lock pliers submerged overnight and the metal turned black. I'm pretty sure that it was not only rusted areas that discolored, all of the metal turned a pretty dark, uniform black (and the light rust was gone). Might have something to do with the steel composition in this 30 year old pair of Craftsman pliers.

    Anyway, put some T-9 on the pliers and they have stayed looking the same: a nice black .

    I still use Evaporust extensively, but since my blackening experience I am cautious to check for discoloration every hour or so during my use of Evaporust.

    I found on my tablesaw that 400 grit is as fine as it needs to go. I tried 600 and do not see any improvement with my ros.
