THIS IS A GREAT PRODUCT FOR DEALING WITH MINOR SURFACE PROBLEMS ON PAINT, GEL COATS, AND PLASTICS. IT WILL REMOVE OLD WAXES, POLISHES AND LIGHTLY EMBEDDED DIRT FROM THE SURFACE. MANY CLEANER/WAXES ACTUALLY TRAP DIRT, ETC. THAT HAVE BEEN PULLED FROM THE SURFACE BECAUSE OF THE HARDENING OF THE WAX AS THE CLEANER/WAX IS BEING APPLIED. ALSO, MANY PRODUCTS CONTAIN FILLERS WHICH DO NOT REMOVE SURFACE PROBLEMS, BUT ATTEMPT TO HIDE THEM. AS THESE PRODUCTS QUICKLY WEAR, THE SURFACE PROBLEMS QUICKLY RE-APPEAR. PERFECT PREP LEAVES THE SURFACE CLEAN AND SMOOTH SO THAT IT LOOKS LIKE IT HAS BEEN WAXED. FOR BUFFER USE, THE #3 WHITE PRO FINISH PAD IS RECOMMENDED.
