Million Dollar Question!


Clay removes above-surface bonded contamination through the mechanical action of the clay bar rubbing against the vehicle surface. Detailing clay abrades the contamination, wearing it down in some cases, as a result of this mechanical action. However, detailing clay is not abrasive to the paint. The use of an approved clay lubricant prevents marring of the paint. The removed contamination sticks to the clay and is removed from the paint.

Detailing clay formulation determines the optimal function of the clay and its potential to do damage when used improperly.

As an example, a professional grade clay bar thatís designed to remove paint overspray is very firm and contains abrasives equivalent to heavy rubbing compound. Used properly it will remove heavy overspray without damaging the paint. Used improperly, it can leave some pretty significant surface marring. Thatís why itís a professional product.

Most consumer grade detailing clays are designed to be used as an annual or semi-annual paint maintenance tool prior to polishing and waxing. At this frequency, these detailing clay products work great. Simply use the clay as part of your major detailing regimen.

The problem we were beginning to see is that many car enthusiasts wanted to clay their vehicles frequently; as often as monthly. At this rate of use, some consumer grade detailing clay can begin to dull clear coat finishes. After all, it is an abrasive!
