Microscopic Matter Dulls PaintNot easily washed off and invisible to the naked eye, particulate debris like rail dust, brake dust and industrial fallout will bond to automotive paint, and distort the reflective quality of the surface, dull its gloss and may eventually cause oxidation. 3M™ Perfect-It™ Cleaner Clay removes these difficult contaminants better than washing alone.Microscopic debris penetrates a vehicle's clear coat every day, especially in areas especially prone to pollution. This debris can build up over time, and easily remain even after the vehicle has been washed. 3M™ Perfect-It™ Cleaner Clay easily removes road dirt, tree sap, pollution, paint overspray or road paint spatter - difficult to get off the surface by other means - to restore a "like new" surface.3M Science.
