Light weight patching, caulking or sealing composition which is especially useful for filling dents in automobile bodies. A conventional liquid thermosetting polyester resin, generally containing solid particulate inorganic filler, is additionally filled with small hollow filler particles. The composition is rendered thixotropic, storage stable, spreadable, and selfleveling by dissolving in the resin minor amounts of cellulose acetate butyrate or related mixed esters of cellulose. After hardening, the composition is easily sanded to the desired contour; paint applied thereover forms a smooth coat, which, surprisingly, is free of pockmarks. |
