Guys,
I’m putting the last sheet of shiny corrugated aluminum roofing, made from roasting pans, on a couple buildings.
I have chemicals for rusting steel, oxidising brass, blackening pot metal, etc…
But nothing touches this shiny stuff.
What do you’all use to weather shiny brand new aluminum roofing?
I don’t want paint, then I’d have to zinc-chromate the alum just to get the paint to adhere good.

I’ve used muriatic acid, but it’s a little tricky and you have to be careful with it.
I use a can of Rustoleum or Krylon primer…theres also a RUST system in the paint can section…soem stuff that does copper patina and pewter looking stuff…browse the spray bomb aisle at Wallce World…
