Function of primer surfacer grey is to even out all minor surface defects, still left on the primered and puttied surface of a vehicle. It has ideal balance between the binder and the pigment/extenders so that it can achieve evenness on a surface and also can offer a non-absorbent finish so that subsequent coat of a finishing paint does not penetrate its film, thereby loosing gloss. The above primers contain no added lead or chromate.
