RCP's Clay Red in Medium grade is a must-have for the decontamination step of a detail, deep cleaning your paint before polishing or sealing. This medium clay bar removes embedded contaminants like tree sap, insect residue, paint overspray, road tar, rail dust, and stubborn dirt that a regular wash cannot lift. We recommend using it with a clay lubricant or soapy solution, gliding the bar gently across the surface until the paint feels perfectly smooth. The result is a super clean, super smooth finish that is ready for polishing and protection. This clay bar paired with a quality clay lubricant and a plush microfiber towel will take your detailing experience to the next level.
