P21S Paintwork Cleanser is a great way to prepare your paint before sealing or waxing. This pure polish helps cleanse the clear coat so it is free from embedded debris and other contamination. Over time contaminates will become lodged in between the micro ridges of the clear coat and they will often not be removed with a simple wash and dry. The contaminates and swirls cause light to not pass directly through the clear coat, which prevents a deep shine. This polish will help remove imperfections, surface contamination, oxidation, old wax and sealant while buffing the paint to a high shine. The Paintwork Cleanser's smooth cream goes on and off very easy and makes a great addition to any detailer's arsenal.
