This product is the easiest way to bring back your faded black plastic bumpers to their original looking color. Applies easily with the built-in foam-tip applicator which means you don't have to mask off the painted areas of your car when using this product. It permanently dyes vinyl and rubber trim, bringing it back to a new appearance. Use on bumpers, side molding, tires, mirror housings, door handles, spoilers, and faded engine parts. For better results use our Rubber Prep first to remove oil, grease and old vinyl dressings. You're gonna love this.
