Abstract: A wipe-on clear protectant based on polyurethane is provided, which provides a finish that is durable and long lasting, is not injurious to the leather or artificial leather on which it is applied, in the instance of use on vinyl, impedes, rather than fosters, plasticizer migration, and is not slippery or tacky to the touch. In the preferred composition, polyurethane is dissolved in isopropyl alcohol, and ethylene glycol monobutyl ether is added, and the resulting liquid is wiped as a clear liquid onto the surface of the cleaned and dry leather or artificial leather produce which is to be protected. The finish dries clear, even, waterproof, smooth and without tackiness in less than thirty minutes.

Abstract: A method and apparatus for repairing plastic and vinyl materials utilizes a heat curable repair compound and a hand tool which supplies a narrow jet of heated air. The hot air tool receives air at a constant low pressure from a regulated air supply and includes an electrical heating element which heats the air passing through it to a temperature sufficient to cure the repair compound. Damage to plastic and vinyl materials can thus be repaired by trimming the damaged area, filling the trimmed area with the heat curable compound, heating the compound with the jet of air from the tool and finally, texturing the surface by the application of graining paper to the patch.
