## Description

desertcart.com: Birchwood Aluma Black - Cold Brush on Blackening Solution for Aluminum alloys Traditional Patina Blue and Black Oxide Touch-up (1 Gallon) : Everything Else

Review: Blackest color I needed - When I opened and saw a light blue liquid, I thought I had the wrong stuff but it turned black right away!!!!!
Review: Not a complete coating system - Does what it’s supposed to but it’s not a complete system. Be sure to read the instructions on the manufacturers website. You need a surface sealer. You cannot get a durable black coating from this product alone. The finish rubs off easily. I wish it were sold as a package with an appropriate sealant.
