So, I found this product while doing a project foor my son's wedding, (http://www.steelfxpatinas.com/). I contacted the owner and asked about using the product on Chrome and was told that due to the slickness of chrome (and stainless steel) he didn't recommend using it on those items. After reading Chain's sticky on painting chrome, I'm thinking about trying it out on on some spare parts. I really dig the "case hardened" effect this stuff leaves on mild steel. My question is does anyone know what Metal HD uses as a base for their chrome components?
