Waxoyl and other schutz products to be used on car body repair and maintenance. Use underbody seal to create a protective layer for the underside of your car. This will minimise rust formation and general wear and tear from driving on dirty or wet roads. You can also spray behind doors, chassis and sills to remove rust and create a new rust-protection layer for your car. Protect your investment by careful maintenance and care, like using Waxoyl or other car body seal.
