Under Gone Undercoating Remover Aerosol 17 oz
Product Review (submitted on February 21, 2013):
This product is probably only good for certain types of undercoating. I'm guessing if it is rubber, this stuff won't do anything but clean the rubber. Eastwood should clarify this in the product description, and perhaps provide some type of "test" to determine whether this product will work on your undercoating.
