ABSTRACT OF THE DISCLOSURE According to the present invention a kit for repairing chips in porcelain enamel is provided which allows the home handyman to provide a high quality finish to chips in porcelain enamel finishes commonly found on stoves, fridges, sinks, bath tubs, etc.. Fundamental to the kit is an aerosol container containing an acrylic lacquer, an acrylic enamel, and a suitable thinner wherein the ration of the acrylic lacquer and enamel to the thinner is approximately 1 to 1 and wherein the amount of acrylic lacquer, as a percentage of the total acrylic lacquer and acrylic enamel, is between 60 and 78%. The particular percentages of both acrylic lacquer and acrylic enamel must be maintained within a specified range in order to provide the finished surface with suitable characteristics which are achieved due to a combination of the brittle like characteristics of the acrylic lacquer and the softer more pliable characteristics of the acrylic enamel. The aerosol spray is advantageously packaged in combination with a metal primer and a metal filler which will allow the damaged area to be prepared to assure good hold down characteristics of the filler which is applied to the damaged area for subsequent finishing with the contents of the aerosol spray. The finish provided by this system is of a much higher quality than achieved by the prior practise of merely applying a soft, colour matched enamel which has poor adhesion properties and has not functioned satisfactorily.
