An apparatus for waxing vehicles for use in conjunction with commercial "car wash" operations. Vehicles are transported by a chain driven conveyor mechanism through a wax application station, passed to a second conveyor mechanism for movement through a drying station, and on to a third conveyor mechanism for passage through a polishing station. A computer system controls the waxing process and operates various pneumatic positioning devices, positioning wax application heads, drying blowers, and polishing heads adjacent the vehicle, a using knowledge of the size, shape, and dimensional parameters of the vehicle. These parameters are stored within the computer system according to manufacturer, model, and year, specified when the vehicle enters the apparatus. Wax application heads used in the wax application station and polishing heads used in the polishing station operate in a circular pressure-sensitive manner resembling the hand orbital waxing motion used to manually wax a car, and air cylinders on each head drive a rotating-translating shaft which urges the head against the car. The wax application heads have removable porous pads over a grooved rubber mandrel head, and apply liquid wax flowing in the grooves to the car. Electromagnetic sensors located on each wax application head inhibit the application of wax to non-metallic areas of the car by inhibiting the flow of wax and causing the head to retract from the vehicle. The polishing or buffing heads are similar, but apply to wax.
Currently dental laboratories use a lathe for the polishing of the dental crown. Such lathes use a polishing disc brush mounted on a rotating shaft and which generally cannot polish the deeper parts of the surface of the appliance without wearing down the surrounding anatomy. The present device provides a brush which uses an orbital motoin to thereby better preserve the anatomy of the crown.
A spray wax concentrate adapted to be applied in a highly diluted state in an aqueous spray to a surface, such as a vehicle surface, in the hot sun comprising about 2 to 10 wt. % of a fine polishing powder, of about 10 to about 40 wt. % of mineral spirits, of about 0.5 to about 3 wt. % of a dimethyl silicone fluid polymer, from about 0.5 to about 1.75 wt. % of an alkanolamide surface-active agent; from about 1 to about 1.75 wt. % of a higher alkyl amino functional group substituted dimethyl silicone polymer wax, and the balance, water, to obtain a total of 100 wt. %. The spray wax concentrate is preferably applied as pressurized, turbulent aqueous spray containing about 1 part by volume of the spray wax concentrate and about 40 to about 100 parts by volume of water.
