Etching/patinating stainless steel



(-----) January 9, 2008

I make custom patio furniture and copper tables. I use a variety of finishes on the furniture, mostly powder coat. The copper is chemical treated and then clear coated. I have a customer that has a water fixture and a custom grill that is accented in stainless. She came to me to see if there is a way to tarnish or age the metal without tearing it out and powdercoating it. I have used some rust accelerators and other chemicals but have no idea what would work on stainless. My only idea is to radial sand it and pain it on site with a low gloss clear. If anyone has any info I would appreciate the help.
