    Patent number: 4416068
    Abstract: The present invention concerns a method and an apparatus for accelerating the drying and/or curing of filler material, primer and top-coatings in connection with touch-up work on car bodies.According to the apparatus of the invention, grinding, filling and spraying are accomplished in one and the same booth, whereupon a carrier containing infra-red heat radiators and/or heating-elements and/or nozzles is traversed over the car, whereby controlled heat-energy is supplied to the surface accelerating drying and/or curing process of the surface treatment material. For supplying sufficient heat-energy to the front and rear parts of the car, special reflectors are located in front of and behind the car for reflecting heat-radiation from the carrier.
