GYEON quartz Cloth Q&sup2;M ClayLube 500 ml QM ClayLube has extreme slickness which reduces friction and prevents the clay from grabbing and marring the surface, instead the clay will slip over it to reveal smooth paint. Ideally used with QM Clay for best results, but it can be used with any clay bars, cloths or discs to lubricate. QM ClayLube can be diluted down as far as a 1:10 ratio, which offers great economy, without impacting on its high performance and still allowing good lubrication for the clay to do its job.
