Any Suggestions on what products or types to use on a front bumber that looks clean but has a rough feel to it. I want to prep the car for a Chicago winter and protect it as much as possible. I also have been researching how to polish the headlightlight covers as they have some rough spots as well. This is 2001 Deville that has gone thru 2 winters in Chicago and needs a little TLC. Thanks for the help. Only a menber of the forum for three days and already have gained so much info. It great to be talking to other Caddy lovers. My first but not my last ( I saw the new convertible, WHAT A SHARP RIDE. To bad it's a two seater, I'm pretty sure my wife would draw the line at riding on the roof after I put my four year old in the other seat. Plus it would really screw up the aerodynamics.
