A composition for use in a touch-up paint for repairing chips or scratches in paintwork comprises fumed silica, a polymeric resin dissolved in a solvent, and a compatible diluent having a lower evaporation point than the solvent. The resin may be an acrylic resin, the solvent may be methyl propyl ketone, and the diluent may be acetone. Typically, the silica is a hydrophobic fumed silica coated with a silane. Ideally, 50-100 pbw of the composition is mixed with 100 pbw of a pigmented proprietary solvent based paint, e.g. a polyester resin-based paint, to form the touch-up paint. A preferred composition comprises 100 parts acrylic resin, 80-120 parts methyl propyl ketone, 100-250 parts acetone, and 1-4 parts fumed silica. A kit comprising the touch-up paint and a blending solution for blending the touch-up paint with the surrounding surface is also disclosed. The blending solution may comprise a xylene and naphtha. |
