The Koch Chemie Clay Spray will provide you with proper lubrication while using a clay bar! A clay bar will grab and pull embedded contamination from the surface, but if you do this without proper lubrication, you do risk marring the surface. The specialized formula of Clay Spray will encapsulate this contamination providing you with excellent lubricity to safely pull it out of and away from the painted surface. This will greatly reduce implementing any swirls, scratches, and marring during the claying process. Once finished, any residue is easy to wipe away with a microfiber cloth. Allow your clay bar to easily glide across the surface with the Koch Chemie Clay Spray!
