Maybe one of the new nano coatings?
I use pinnacle diamond coat (I think it’s called) on my 15 corvettes wheels. Supposed to “bond” with the wheels finish and create a protective barrier.
My process was to use an iron out product, then Wolfgang polish, then Wolfgang sealant, then nano top coat (after sealant had cured). So far so good.
Also have had friends use cquartz and like it. Either one will make the brake dust almost wash right off.
