Your spray strokes should be made with a free arm motion, keeping the gun at a right angle to the surface at all times. Arching your stroke will result in uneven coverage and excessive overspray. If your nozzle is arched at a 45-degree angle at the beginning or end of your stroke (as shown here) versus a 90-degree angle, you'll be losing about 65 percent of your sprayed material as overspray; the gun always has to be at a 90-degree angle to the surface for proper coverage!

This works out to a savings of $124.55-and that's for the name brand's Economy Line of paint and material. The cost savings for Summit Racing's paint system versus the brand name's high-line of product would increase your savings three- or four-fold at a minimum! In fact, the name brand's gallon of the same color red urethane sells for over $350 alone! And believe me, it doesn't spray or look any better than Summit's $79.95 gallon!

And here's another thing to keep in mind-when you opt to pay a paint shop to do your spraying, you better believe you're going to get charged name brand prices for the material, no matter what they use!

Equipment Setup And Use
The initial setup of a brand-new, "out-of-the-box" suction-feed spray gun is pretty basic. What we tell you here should more than suffice for your initial spray experience, and we're sure that once you begin to get the feel of the gun, you will then be able to make some adjustments to flow, volume, and pattern that will be more to your liking.

First, attach the cup to the gun following the manufacturer's instructions. Once the gun and cup are together, go ahead and mix up the material to be sprayed. Make sure to follow the mixing instructions, adding the correct amount of thinner/reducer and activator if necessary. Then strain the mixture into the cup, and tighten the lid. If they aren't already, turn the spray gun's upper adjusting knob (fan control) to the closed position (fully in), then do the same with the lower one (fluid control). Connect the air supply hose to the gun, and initially set the air regulator to the pressure recommended by the material manufacturer.

Next, back both adjusting knobs out (counterclockwise) until the first thread of each is showing. Using a piece of cardboard or sheetmetal as a test surface, point the gun at the surface and give the trigger a 1-second pull. What you'll most likely see is a small, rather round spot of paint on the test panel.
