Car Touch-Up Sprayer for 25c
BEFORE you buy an expensive spray gun and compressor, try an artist’s fixative atomizer, available for 10c to 25c at art and drafting supply stores, model shops, and at many hobby and craft shops. Used by artists and architects to spray their pencil and chalk drawings with fixative to prevent rubbing, this gadget can perform many small painting jobs, using only lung power.
It works on the same principle as any compressor-type sprayer, with you supplying the compressed air. A jet of air is forced across an orifice, creating a low pressure area which draws the paint mixture up the vertical tube. As the paint comes out of the tube, it is literally “blown into bits.” The atomizer can be cleaned without disassembling—merely use a pipe cleaner dipped in thinner (C).
Of the 3 types shown (A) the type that comes mounted in a standard jar top is most handy where the same kind of paint is used repeatedly. However, the simple, 2-tube affair with a folding joint is preferable, as it can be adjusted to give a coarser, faster spray merely by bending the tubes closer together than the normal right angle (B).
Generally, any paint of the right thickness for brushing can be sprayed in this manner by adding to it an equal quantity of thinner. If the spray seems thick and clotted, add more thinner. The more thinner used, the finer the spray that results, but too much thinner will make it “run.” Too little thinner will make it too difficult to blow. Use alcohol to thin shellac, turpentine for enamel or oil paint, lacquer thinner for lacquer or for model airplane dope, and water for casein paints. Otherwise, use whatever thinner is recommended on the paint can. Stir or shake the mixture often during use, to prevent settling. Always spray out-of-doors if possible, and on a windless dry day. Breathe through a water-dampened handkerchief if spraying indoors for any length of time. Prop up the object to be sprayed so that it will not overturn during application.
There is no limit to the number of paint jobs that can be done this way: automobile retouching, model airplane doping, shellacking, furniture retouching—in short, any job where your brushing skill is inadequate, or where fast-drying paints are difficult to brush on without leaving tell-tale brush-marks. However, it is not advisable to try to paint your entire car by lungpower; a fender or two is enough to try, at least for one “blowing.” A final word of warning: Don’t try a plunger-type insect sprayer. The spray will not be uniform, and you cannot aim and push the plunger without missing the spot you want to hit.—Noble D. Carlson.
