You know... maybe it was just the fact our bumpers were really bad but when I tried that on a car I didnt accomplish anything but creating a sticky mess, haha. :scratch:
Haven't done it myself, but a good friend did and it came out looking a lot better than when he started. His bumper wasn't badly rusted or pitted, just dull with discoloration. He said rather than soaking the foil in Coke just dip it, and make sure to use it shiney side out. Since my Dart bumpers are a lot bigger than his Mustang bumpers I don't think it would work to well on mine, they'll stay as-is until I can get them re-chromed.
