The Auto Finesse Detailing Clay Bar comes as a 200g block and is made from an ultra-fine grade of natural Kaolin clay. This structure allows it to be both more effective against contamination, and less abrasive on sensitive paintwork than common polymer clays. It will efficiently remove both organic contamination (tree sap, mineral deposits from rainwater, protein deposits from insects and bird droppings,) and inorganic contamination (light tar and iron deposits, industrial pollution, paint overspray, etc.) on practically any hard surface. Paint, alloy wheels, glass, bright work trim, and even gloss-finish plastics can all benefit from being clayed.
