Less mess is the goal when it comes to applying tire dressings. Cobra Flex Foam Tire Dressing Applicators feature Flex Foam TechnologyTM which hugs the curve of the rubber to apply an even coat of tire dressing with no drips or pooling. Cobra Flex Foam Tire Dressing Applicators are made of a unique foam composition that conforms to the curve of your tires' sidewalls. Foam applicators that are precut into a curve might not match the curvature of your vehicle's particular tires. The top layer of foam on the Cobra Flex Foam Tire Dressing Applicator is made of dense, closed-cell foam that will not absorb tire dressing. Grip the applicator on this yellow foam to keep your hands clean.
