Gummi Pflege is a special rubber treatment that conditions rubber weather seals on car doors, windows and trunks - reducing squeaks, rattles, wind noise and potential water leaks. Gummi restores color to dried out rubber and keeps them elastic while protecting them against the damaging effects of heat, freezing temperatures and UV rays. It uses a petroleum-free, water-based formula. Easy-to-use shoe polish type applicator makes application simple without the mess.
