whats the best bumper product to keep it to its original form? atm I'm using auto glym bumper care.!!

gr rust has come back!! i have rubbed the area down sprayed laquered ! and it has come back! and advice ?

only way to kill rust for good is to cut it out and weld clean metal in. however using a rust inhibitor like kurust will stop it for a good long while. prep is key. i find using a soft wire brush attachment gets most of the rust out. you can also get nylon impregnated ones which are superb. once you've done that apply the kurust, skim with filler, sand back, primer, paint and laquer!
