I got my answer today when I went back to work. I asked 1 painted and he said yes I could clear it. If I used some sss adhesion promotor. It lays out a thin clear film and protects the metal, anything will stick to it and it will stick to the aluminum.
I asked the other painter and he said no it wouldn't work b/c alum. Is porous and the polish will make the clear bubble after a few weeks.
He said the onlu aluminum you can clear is a fresh machined part.
He told me zoop seal would be the best bet, but it hasn't been tested,tried and true.
I can't just keep polishing it b/c the project is a 35-40 tour style bus. The front,back,sides and top are all alum.
My plan was to polish it to a mirrorlike finish.
Then clear it with some blue ice pearl, then clear that and polish it to a nice shine.
Thanks for the help though.
