Abstract
A stick for the application of a colored composition to scratches, nicks or chips in a painted substrate, such as a vehicle body, is provided. The stick fills in, masks and seals the scratches, nicks or chips producing a finish that has a final appearance substantially similar to the surrounding vehicle finish and maintains water and rust repellency over repeated washings and exposure to the elements. The stick includes a structuring substance containing one or more waxes, a pigment, and a wax soluble liquid silicone polymeric material. In one preferred embodiment of the invention, the stick comprises an acid wax derived from montan wax, a paraffin wax, carnauba wax, pigment and a wax soluble liquid silicone polymeric material including polydimethyl siloxane and hydrocarbon groups. In another embodiment of the invention, the stick is conveniently mounted in an applicator of the lipstick holder type. In a further embodiment of the invention, a method for filling in, masking and sealing the scratches, nicks or chips in a painted substrate using the stick of the present invention is provided.
