Eastwood Rubberized Rust Encapsulator - Black Aerosol
Product Review (submitted on August 26, 2012):
I sprayed the floor pan of my car with this product. It went on well, but the nozzle did clog a couple of times. Just used Pre spray or acetone and nozzle uncligged easily. fills cracks and seams, also did a good job of heat and sound reduction. I will use again, but the price could be better.
