Washing your car can always be a gamble between achieving a highly desired glass like finish and a dulling the paintwork by adding swirl marks and scratches, as if your sponge/mitt touches the bottom of the bucket picking up sharp dirt, you are more likley to abrade your paint work than polish it. Not any more, ScratchShield creates a one way filter system providing a barrier between your sponge/mitt and unseen harmful dirt and debris lurking at the bottom of your bucket.
