Pack of 2 x Clay Block Pad Our clay block pads are designed to remove insects, tree sap, fall out, metal filings, brake dust, over spray and other heavily ingrained contaminants on your paintwork and glass. They designed for use with a quick detailer or clay bar lubricant. The main difference between this pads and a traditional clay bar is that they are long-lasting and are economical in use. They last far longer than a clay bar because they are continually cleaned in use, and can be cleaned and re-used rather than having to fold and then disposed of quickly like a traditional clay bar. To use, simply wet and lubricate a panel, and gently move the block over the panel. Occasionally rinse and clean the block in a bucket of clean water. Note – marring still may occur with this clay block, similar to the effects when using a clay bar. Marring can be machine-polished out, however, it is recommended that it is tested on an inconspicuous area prior to extensive use, especially on softer paintwork.
