Abstract
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.
