This versatile two sided brush by Chemical Guys is ideal to use on those tough to clean small areas. Clear polypropylene bristles are heat-set into a heavy duty polypropylene handle for professional long lasting durability and, although it is heavy duty, it is gentle on both the exterior and interior of any vehicle. Hundreds of bristles provide just the right amount of heavy duty scrubbing that is still gentle enough for both interior and exterior purposes. The fine detailing abilities of this brush means it is perfect to uses around emblems, moulding, trim, door handles and more.
