Conforms to the shape of tires. Non-absorbing foam evenly spreads tire dressing on the tire, using less tire dressing. The bottom of the curve of the applicator fits between the tire and rim eliminating tire dressing from getting on the rim. Also excellent for low-profile tires. Washable and reusable. 2-3/8 in x 3-5/8 in x 1-1/2 in.
