The aluminum radiator tanks and side panels on some of our trucks ( 1920's and earlier) need replacing. Looking at getting replacement aluminum sections cast or fabricated up, but either way the finish is too polished and bright, and does not match existing sections. It would be nice to have that aged look to the whole radiator unit.
Any ideas as to methods in oxidizing new alloy to make it look old? Caustic soda or similar?
I realize this goes against the general trend of polishing an item up and being shiny so it looks good, but I want the image of a light grey finish.
