Abstract of US9399313 (B1)：
The present invention is an improved method of manufacturing rubber wheels and composition thereof used on a portable vehicle adhesive remover for removing pinstripes, decals, side moldings and other items adhering to a vehicle without damaging the original paint of the vehicle. The improved method of manufacturing rubber wheels may comprise masticating approximately 100 parts of rubber in a mixer and synthesizing a rubber compound by mixing in at least 8 parts of activating agents, less than 60 parts of processing oil, between 0.1% and 1.5% by parts of cross-linking agent, and at least 1 part accelerating agent. The improved method may also comprise vulcanizing the synthesized rubber compound in a mold to produce a rubber wheel having a Shore A hardness between 50 and 60.
