When you use Clay Sponge to detail and polish your car, it can quickly sweep away the surface dirt (such as heavy oxidation, heavy rain water stains, ferrous powder, light rust, brake dust, pollen, the effects of acid rain and tree sap ect.) from your car and leaves a silky smooth paint finish. The regular clay bar in the past provides you with 1-2 times usage only, but the new Clay Block serves you up to 15-20 times, and the result is even better compared to the clay bar! This the investment you want to try to get a perfectly smooth, detailed finishing car look! Clay Bar Sponge applies to cars that with any color. however, it could potentially leave light micro-marring to the surface that would then be corrected when polishing the vehicle for a silky smooth finish. Magic Clay Sponge Bar enables you to clay the entire car in a fraction of the time that a traditional clay bar would take. Normally, it cuts your two hours claying time to about 45 minutes and prevents your shoulders, elbows, arms and hands from wear on.
