I tried Auto Tech Urethane Parts Stripper 2 18 oz cans of Metylene Chloride (active ingredient). It took of a portion of the paint off. I used a can of overspray remover also, but it did not do anything.

The Urethane parts stripper does sofen up the bumper, but it is supposed to go back to how it was within 24 hours.

I am going to buy some that will brush on so that It can do a better job. Any more ideas?
