works great when you follow instructions
My parts didn't do well so I tried the recommendation of using muriatic acid first, and the difference was huge - worked well and worked fast! Make sure you follow the instructions for using distilled water, too. It's cheap and easy and makes a big difference. Compare this to many platers that will charge $250 lot charge for the same end result.

blackened stainless pistol for low reflection
The Caswell Stainless Steel Blackener worked absolutely awesome. I was shocked at how well it performed on my stainless steel 1911 pistol to tone down the reflective glair. I would recommend this to anyone needing to darken any stainless item. Caution, as with any of these chemicals, fumes can be an issue. Use in a well ventilated area outside of your residence.
