Under Gone Undercoating Remover Aerosol 17 oz
Product Review (submitted on December 10, 2011):
I first tried to remove the factory undercoating on my 68 chevy pickup cab using a spatula and a sturdy scraper tool. It wouldn't even scratch the surface! Then I used the Undergone...and what a difference. I just let it soak in for about 2 minutes and then with just the spatula it started coming off. It did take a little muscle behind it, but I was able to remove a 5 sq. ft. section in about ten minutes. Undergone made it come of with ease!
