Works like the Gliptone Body Bar (clay-type-product) to quickly and easily remove "above-the-surface-contaminants" such as scuffs, rail dust, bug residue, water spots, paint overspray, hardened tar and sap. Glides on and off easily for slick finish. Lasts up to 4 times longer then clay bars. No reshaping required. Easily cleans off if dropped.
