The safe removal of the bonded contamination from you vehicles bodywork and windows that washing alone cannot remove.
Road tar, tree sap, insect remains, paint overspray, industrial fallout and acid rain deposits are all enemies of your paintwork, regular washing removes loose dirt but not these contaminants. If left, these pollutants will eventually oxidise, burn or rust through, and eventually destroy your vehicles paintwork.
WHAT IS A CLAY BAR AND HOW DOES IT WORK?
Detailing clay is, not surprisingly, not actually clay. It's in fact a mixture of soft plastic resin (polybutene) and abrasive particles of varying grades. Detailing clay is used along with a lubricant which allows the clay bar to glide smoothly as it is rubbed over the paint surface. Because these contaminants are on the surface of the paint they are exposed to larger abrasive forces than the paintwork, this results in the contaminants being abraded away without damaging the paintwork.
HERE IS AN EXAMPLE OF THE PROCESS!
