IPELY car detailing clay bar is a synthetic plastic putty that physically pulls embedded dirt out from your car’s paintwork.<br> Foreign particles block wax from sticking to the paint, making it last for a shorter time and not shine as bright.<br> The rough feeling on your car’s exterior is pollution, industrial fallout, and environmental contamination stuck in the pores of the paintwork.<br> Decontaminate the surface with a clay bar before putting on a new coat of wax, or polishing any exterior paintwork.<br> Polishing with any rough contaminants grinds them deeper into the paintwork, causing more marring and scratches as they clog and destroy your expensive buffing pads.<br> You can use the clay bar on any exterior car part that is shiny or clear. Use the clay bar to decontaminate car parts such as:Paintwork ,Glass ,Clear optical plastics ,Wheels ,Carbon fiber<br><br> <b>NOTE:</b> There are certain parts you should not use the clay bar on, such as:Matte paintwork/vinyl wraps,Textured plastic trim,Rubber (door / window seals, tires) <br>
