My family has a fleet of 10 semi tractors, all of which are in show condition. My first job was to polish the aluminum bud wheels and allof the chrome and stainless on the trucks. So I think that I qualify to answer this question. I wouldn't use never dull on chrome, because it doesn't leave the chrome in desireable lustre. Get yourself some turtlewax chrome cleaner and polish. Rub it in thouroughly the first application then let it haze and dry. Then apply a second application over this and rub off then wax the wheels if you want it won't hurt. but chrome is the easiest to maintain. Just be happy that you don't have polished aluminum wheels.
