The one polish I live for is "FLITZ" it comes in a silver colored tube of about 6 oz's and is very expensive, but it goes a long ways in polishing metals, plastic and fiberglass... this tube has lasted me a while and I swear by it... made even my wind shield glass guard bite right up and look awesome... The biggest impact was on polished metals, not chrome, the chrome stuff came out sweet, but the polished stuff really shines. It even cleaned my glass lens covers for the headlights. took that dull looking film right off... Remember FLITZ...
