So many times we need to spray paint only a part of our models, such as a cowling or wheel pants, but the colors we need or the type paint we want to use are not available in a spray can. Yet, we find it a major task to drag out the big compressor and the spray gun. There is a simple, inexpensive, and effective solution: Use the “Preval” Spray gun. It is a small aerosol powered spray gun attached to a 6 ounce glass jar. The spray gun unit is sold as Preval part #267 and costs about $7; replacement power units, part #268, cost about $3. You can find these at auto paint and body supply stores. “Let your fingers do the walking.” (http://www.prevalspraygun.com/)

          Simply mix your paint in the supplied jar and spray as you would using a can. When done, insert the pick up nozzle in some solvent and spray clean.
