This kit contains a Surface Detailing Clay Bar together with an instant detailing lubricant (Rapid Detailer). Use in conjunction to remove embedded road grime, tar, tree sap, overspray, industrial fallout and other common paint contaminants. 
 
The Surface Detailing Clay Bar is a specially formulated clay compound that quickly and safely removes contaminants that are trapped on the paint surface. The clay works by 'grabbing' microscopic particles and pulling them free from the surface leaving an ultra smooth finish in preparation for polishing.
