My mountys rear bumper has developed the typical rust spots on it, meaning its not salvageable. Body shop quoted me $500 for replacement about a year ago when i first noticed it bubbling. Now its flaking off and its time to do something about it. I'm thinking of buying a new bare steel bumper and painting myself. My question is are the spray cans of paint you can order online by the color code any good? I dont have a compressor or spray equipment. Also if the door tag lists LL and LD as the paint codes, LD med wedgewood blue metallic would be the lower trim correct?
