OK, this question is for the guys/gals who know how to take the dullness out of aluminum. I run a streetrod with tons of bling-bling. When I polish my flat aluminum valve covers with whatever (Bushe's alum. polish, Semichrome, Mothers), I can't get rid of the haze. I've tried all kinds of polish and every towel/cloth I can think of. What do you do to get rid of the haze on "show" aluminum? Thanks
