The Chemical Guys Black Hex-Logic pad is a 4in zero cut finishing pad for applying waxes, sealants and glazes after the paint has been corrected. Its ultra-soft foam removes no paint, so it is the last pad used in a machine routine, laying down an even coat of protection without introducing swirls. The 4in face works well on mirrors, pillars and bumper sections, while the rounded profile, bevelled edge and V-cut channels help it follow body lines, keep the backing plate off the panel and draw in cooling air. Pair it with a wax or sealant, a hook and loop backing plate sized for a 4in pad, a pad cleaner and plush microfibre towels for buffing.
