Claim:
1. A method of providing chip resistance to a coated surface of an object, the method comprising: improving chip-resistance of the object by permanently adhering a transparent chip-resistant film to the coated surface, the chip-resistant film being transparent, colorless bearing no design throughout, the chip-resistant film comprising a composite substrate and a pressure-sensitive adhesive, the composite substrate comprising (A) an ionomer layer and (B) a polyolefin-based polymer layer adjacent the ionomer layer, the film having a strength at the upper yield point of 10 to 40 N/10 mm, wherein the pressure-sensitive adhesive is in direct contact with a side of the polyolefin-based polymer layer of the composite substrate that is opposite the ionomer layer and further wherein the chip-resistant film improves the chip-resistance of the object without obstructing or altering appearance of the coated surface of the object.
