Rubberized Undercoating Aerosol 18oz
Product Review (submitted on April 1, 2012):
Sprayed this on top of rust encapsulator on frame of a 2008 F550 and it came off within a year. Encapsulator stayed on and looks fine. The undercoat was put on about a month after the encapsulator and the truck hadn't been on the road yet to pick up any dirt on the frame. I use many of the Eastwood products and paid the extra cost of over the counter products due to the results I've had with them.
