Under Gone Undercoating Remover Aerosol 17 oz
Product Review (submitted on June 11, 2011):
I spent around 8 hours on the bottom of my car and wasn't even a third of the way done. So I thought that I would give Under Gone a try. Well it didn't even touch the undercoating on the bottom of the car and now I have 7 cans that I can't even use. I would say save yourself some the money and get back to the grinder and wire wheel.
