As your ride’s exterior ages, rubber, plastic and vinyl of all colours will dry, crack, flake and deteriorate. This oxidation can be stopped and reversed with Mothers Naturally Black, our favorite auto care concoction. This trim treatment is great for bumpers, moldings, louvers, window trim, vents, seals, skirts, door handles, wiper arms—anything that’s plastic, rubber or vinyl. Apply Naturally Black to sunburnt plastic, rubber and vinyl to revive the factory-new sheen, and then re-treat regularly.
