Abstract
There is disclosed a method and composition for cosmetically repairing a surface void in polyolefin objects. The method involves inserting a repair composition into the void and then applying heat thereto to fuse the repair composition with a surrounding portion of the polyolefin object. The repair composition is a physical mixture of a thermoplastic powder, a resin binder, and a solvent, having a paste-like consistency. The repair composition may be neutral in color, or may contain a colorant to closely match the underlying object. The heating step can be performed with an open flame or with a heat gun.
