### ⭐⭐⭐⭐⭐ This stuff works excellent!
*by S***M on July 29, 2026*

This stuff works excellent! Used it for a bunch of raw steel that I welded up for under-counter brackets, vintage ceiling lighting, etc... Was able to make it look super rustic, without the need to simply paint it black. Depending on how much you use, or how long you leave it on, will determine how dark/blackened the metal becomes.
