  • Why is this metal turning a gray?

    I attempted to polish my intercooler. It looked like the same metal that my turbo was made out of so i hit it with the black, brown, and then white. It gets the mirror finish but it's not chrome looking. It looks like i painted it gray. I am lost here. What the deal?

      Who's the manufacturer of this part? Would they know what it is made of?

      It could be a strange alloy of aluminum.

          It could be Pot Metal (Zinc Die Cast)

          Place a drop of battery acid on the part in a hidden area. If it fizzes violently, it's Pot Metal.

            ok apparently it's 536 aluminum that's painted. I just took some medium grit papaer to it and it worked. Now is there something that i can just brush or pour onto it that will take it off? I can't get into some of the spots with the paper.

              Any paint removing liquid (paint stripper) should work.
