i just picked up some chrome 22s and there is some slight pitting, and 1 wheel has some yellow coloration on part of the chrome, my friend is a mobile detailer and they used this stuff called wheel acid and he says it will get rid of that stuff and he's been sayin hes gonna bring some home but he has yet to. i have good chrome polish that works great but it doesnt get rid of the blemishes. what should i do, ive heard of buffing chrome wheels but i dont wanna burn up the chrome.
