1. In combination:

  • a vehicle having an electrical system, a water cooled engine, and an enclosed body;

    a first fluid spray component storage tank in said body having an inlet end and an outlet end;

    a second fluid spray component storage tank in said body having an inlet end and an outlet end;

    said inlet end of said first fluid spray component storage tank being in selective fluid communication with a source of a first fluid spray component;

    said inlet end of said second fluid spray component storage tank being in selective fluid communication with a source of a second fluid spray component;

    a first electrical heater assembly associated with said first fluid spray component storage tank which selectively heats the first fluid spray component therein;

    a second electrical heater assembly associated with said second fluid spray component storage tank which selectively heats the second fluid spray component therein;

    a first hot water heater assembly associated with said first fluid spray component storage tank which selectively heats the first fluid spray component therein;

    said first hot water heater assembly being in fluid communication with the heated coolant of the water cooled engine of the vehicle;

    a second hot water heater assembly associated within said second fluid spray component storage tank which selectively heats the second fluid spray component therein;

    said second hot water hot water heater assembly being in fluid communication with the heated coolant of the water cooled engine of the vehicle where said first and second hot water heater assemblies are fluidly connected together;

    an air compressor on said vehicle which is in communication with said first and second fluid spray component storage tanks which forces the fluid outwardly therefrom through the outlet ends thereof;

    a heat exchanger tank having first and second heat exchangers therein;

    each of said first and second heat exchangers having inlet and outlet ends;

    said inlet ends of said first and second heat exchangers of said heat exchanger tank being in fluid communication with the heated coolant of the water cooled engine of the vehicle so that said first and second heat exchangers are in physical contact with the heated coolant to cause the components passing through said heat exchangers to be heated;

    first and second pumps having inlet and outlet ends;

    said outlet ends of said first and second fluid spray storage tanks being in fluid communication with the said inlet ends of said first and second pumps, respectively;

    said outlet ends of said first and second heat exchangers being in fluid communication with a spray nozzle for spraying the first and second fluid spray components onto a surface.
