It was aluminum. I did get paid pretty good. I did check out those websites but I couldn't get the stuff quick enough so I stopped at a truck stop and it had acid and the metal compound and polish. I am very happy with the results after I got through my head that you will see the "grain" look...
Ok I got a phone call to detail a bread truck. The problem is the sides, back, and hood are stainless steel. He wants to have a fully polished look. What would I use?
