The sponge is designed to apply tire dressing. Tire dressing is a product that is used to protect and shine tires. It can also help to prevent them from cracking and drying out.
The applicator has a soft, plush surface that is gentle on tires. It also has a barrier layer that helps to prevent the dressing from soaking into the sponge and making it greasy. The applicator can be used to apply dressing to both the sidewalls and the treads of tires.
