The Carbon Collective Exfoli-Block 2.0 interchangeable clay system replaces the need for the use of the traditional surface clay bar. The Exfoli-Block is simple and easy to use, it is to be submerged in a strong shampoo and water mixture and then it can be glided across paint work removing contaminants, tree sap and fall out. The open cell foam interface absorbs the solution and releases it during the claying process which prevents the panel from drying out and creating a safer claying process.
