Claying a vehicle is the process of removing bonded surface contaminants from your car that cannot be removed by washing alone and that need to be eliminated before the polishing process, using a synthetic bar of poly clay. It works by gently pulling and lifting the bonded contaminants off the surface which then become encapsulated in the clay. It’s a process that will give you the best results for a great shine, and most importantly, opens the pores of the clear coat surface so that the wax or paint sealant will soak in deeper to give it that extra depth of shine and layer of protection.
