Product no.: 519100032
Highly acclaimed by Gunsmith and Author, John Bivins, in the March/April 1977 RIFLE. Contains no mercury salts, and is non-toxic. Cuts through grease and oils, making pre-cleaning much less critical. Works fast, 4 to 6 applications 3 hours apart. The resulting brown is fine-grained with excellent color.
Not the results I was hoping for 15/04/2016
Have been trying without success to rust blue a few parts. Not sure what it's doing, but not rusting like it should. Tried once with failure and thought I had possibly messed up on the first run. Stripped everything again degreased and tried a second time. Dismal rusting.... Tried applying a second coat without a boil this time in desperation and it turned the thing black! Whiskey Tango Foxtrot. I'm thinking that possibly a bum batch.
Great Product. Follow the directions. 14/09/2015
Used this on a Series 70 Government Model. Was a little nervous at first but if you follow the directions you'll do well. Just keep going.
Wear gloves during application!!!! You will leave fingerprints otherwise. If you leave prints you'll have to sand back down to the polish you started with. But it can be done.
Two browning applications to start followed by three to four applications with boiling water per the instructions. Used the Brownell's carding wheel and it worked great. Buy it too.
Finish turned out great but I would have polished the flats to a finer grade (600 to 800) to get a little more shine. Resulted in a nice, dark blue color.
So, wear gloves and follow the directions and you'll do fine.
