Abstract: A method and resultant product for bonding a polyester resin to plastic. Preparation of a polyester resin bonded to plastic includes the steps of: (1) grinding the surface of a plastic body to create a plurality of fine plastic hairs protruding from the surface; (2) depositing liquid polyester reinforced with glass over the protruding plastic hairs, whereby the plastic hairs are substantially encapsulated and surrounded by the liquid polyester; and, (3) allowing the polyester resin to cure. Consequently, at the interface of the polyester resin and the plastic, a mechanical cohesive bond is created via the substantial encapsulation of the plastic hairs by the polyester resin.
