I have used the extreme polish.mothers.blue magic,simi chrome.They all work great but the best i have used to date is heavy metal polish they have 3 different compounds
red-coarse compound
green- for heavy oxidized alm,stainless,chrome
blue- for billet,fine polishing high shine.
the thing i like about this stuff it goes on easily and comes very easy,very liquidy and protects good.Also smells like candy.
