i used medium grade and then fine sandpaper, then oooo steel wool, and finished off with "mothers" aluminum polish with a long strip of old jeans, applied the mothers and rapped the cloth around twice and pulled the ends back and forth, i've found that the cloth jeans are made of polishes the best for some reason, washed off all the black stuff then buffed it with an old towel,
and that crossbar was welded to that old bumper, and was very thick and heavy also, and with that solid tow hook thingy im tellin ya it prolly weighs 30 pounds, the new ones like 4 or 5 lbs,
hey 95 i'd offer the old one to ya if ya like it so much, but it weighs so much you prolly couldnt afford shipping hahaha
