Restore a smooth, clean finish to your vehicle with the Chemical Guys Medium-Duty Gray Clay Bar, part number CLY_402. Designed for automotive detailing, this clay bar lifts bonded contaminants that normal washing cannot remove, including overspray, rail dust, industrial fallout, brake dust, and embedded road grime. Its medium-duty formula provides effective cleaning power for exterior paint, glass, and other smooth automotive surfaces when used with an appropriate clay lubricant.

Use the Chemical Guys CLY_402 clay bar during paint preparation before polishing, waxing, sealing, or applying a ceramic coating. Removing surface contaminants helps improve paint smoothness and allows detailing products to bond more evenly. The gray clay formulation is suitable for moderate contamination and is a practical choice for routine vehicle restoration, seasonal maintenance, and professional detailing applications.

For best results, wash and dry the vehicle first, then work on a cool surface out of direct sunlight. Break off a manageable portion, flatten it into a thin pad, and lubricate a small section thoroughly. Glide the clay lightly across the surface until it feels smooth, regularly folding and reshaping the clay to expose a clean surface. Store the used clay in a clean, sealed container and discard it if it becomes heavily contaminated. Always test an inconspicuous area first and follow proper detailing procedures to help prevent marring.
