rilliant Finish Synthetic Clay cuts faster than clay bars thanks to the texture and synthetic make-up of the clay/polymer matrix. A traditional clay bar has only one leading edge to remove contaminants on initial contact. It's blunt. The diamond pattern found in Synthetic Clay's clay/polymer matrix creates more edges and more opportunities to remove stubborn contaminants. The comfortable foam palm pad creates less hand fatigue and is much more maneuverable than clay bars, a win-win for detail-minded enthusiasts everywhere.
