Size:64 fl oz (Half Gallon) Chemical Guys Clay Lubber is the only clay bar spray you will ever need. The clay bar has long been the "detailer's secret" for restoring smooth-as-glass feel to the paintwork on any vehicle-but now the secret is out, and Chemical Guys can show you how to get the same results! As you drive your car around town, things like paint overspray, brake dust, pollution, and industrial contamination land on the paintwork and get stuck in the tiny pores of the surface. The clay bar works by grabbing onto any contamination that sticks onto the surface of your vehicle, then pulls it out as you rub the clay across the paintwork. But to help it glide across the surface without getting stuck or marring the glossy shine, you need a lubricant. This is where Clay Lubber comes into play: simply mist Clay Lubber over the surface to lay down a coat of slick lubrication between the clay bar and your paintwork. Now as the clay bar grabs onto the above-surface contamination stuck on top of the paint, it won't get stuck to or mar the painted finish. Chemical Guys Clay Lubber helps facilitate the best clay bar technique over any exterior surface that is shiny or clear. Use Clay Lubber whenever detailing paintwork, glass, clear plastic headlights and tail lights, or polished metal parts with any decontamination clay tool. Clay Lubber is gentle enough for use on the finest natural detail clay bars, and helps preserve the integrity of the elastic polymer bar. The pure-synthetic Clay Lubber formula is safe for use on any exterior car part that you wash with soap and water, and works with any traditional clay bar or synthetic rubber clay bar substitute. Choose Chemical Guys Clay Lubber to restore a smooth-as-glass feel and extra shine with every clay bar service.
