Clay bars clean paint prior to polishing, removing overspray and contamination on paint, glass and chrome, and shifting insects, brake dust, stubborn road grime, exhaust soot, surface rust, tar and oxidation. Choose a fine-medium bar for normal contamination and a coarse clay bar for heavy contamination. Our carefully selected range of quality clay bars, clay lubricants and associated products will remove tough-to-shift stains and marks during a detail.
