Great product, exactly what i needed to blacken stainless parts
I had a bunch of stainless m1 parts that had all the finish worn off. After cleaning the parts and sandblasting i wiped the blackener on and the parts turned black. It was exactly what i was looking for!

Worked as expected - easy to use
So far have just tested to see how this worked and attempted some touch-up on a previously finished item. Very good match was achieved in the touch-up work. Blacked stainless barrel material quite well. finish seemed durable.

Unexpectedly Great Results
I refinished a stainless steel putter head, using minimal preparation. Cleaned the head with acetone, scrubbed it with fantastic, and then scrubbed it with distilled white vinegar (my own system obviously). Rinsed it and then dipped it in the blackener and scrubbed the head with 3M great and 3M white abrasive pads while it was submerged in the blackener, Pulled it out, rinsed, and let dry. That was it,. Amazing results for just a little work. Not perfect (not the products fault) but I will do it again and again, and try to improve my technique each time. Fun and rewarding.. A fantastic product!
