Undercoating is that layer of thick rubber covering everything under your car to protect it from rust and wear. While this has a number of benefits, trying to remove it can make a person curse its very existence. In the past, this daunting task has been handled with a myriad of grinders, torches, scrapers and anything else that seemed like a good idea at the time, including a long list of solvents. Chemical removers for this job have come a long way, and high-quality products are now readily available to the public. 

Instructions

1. • 1
     Place a piece of cardboard or a plastic drop cloth on the ground, large enough to catch everything that falls from under the car during the work.
   • 2
     Cover all surrounding areas of the vehicle with high-quality masking tape. Undercoating remover can damage painted surfaces.
   • 3
     Put on a pair of disposable gloves and a pair of safety glasses or a face shield.
   • 4
     Spray a coat of high-quality undercoating remover on the undercoating material. The remover will foam up on the surface. Let it soak in until the foam is gone.
   • 5
     Scrape away the loosened undercoating with a metal paint scraper.
   • 6
     Repeat Steps 4 and 5 until all of the undercoating has been removed.
   • 7
     Clean off any remaining residue left behind by the remover, using wax and grease remover and paper towels.
