For the average guy, buying a used car usually means it won't be anywhere near perfect. There's going to be rust and oxidation on the weathered paint, bumpers, trim, etc. Unfortunately, one of the last stops on the list is replacing trim, bumpers, and such. Most even hold off on sending out bumpers to be re-chromed until the last minute. On the other hand, there is a quick fix that gets rid of light rust found on bumpers and trim. Simply walk into the utility closet and grab a fine steel wool pad or an SOS pad (which has to have detergent in it, but will work) and walk outside. Dip the pads in water and then use them to scrub the rust off the metal. It's not going to look as good as a rechromed bumper, but you'll be amazed at what a difference it makes.
