Solid particle contaminants shouldn't be a major problem if you've properly configured your air supply (like we talked about last issue). But, the massive amounts of hot, moist, compressed air that pass through these tools, and the extremely high rpm at which they spin, will. To combat the inherent wear, and to ensure continued performance of these tools, lubrication of some type is a must. To make sure they stay in tip-top condition and are always ready to use, you've gotta keep them oiled! This can be done in one of three ways: The first is to add a few drops of air tool oil (through the quick-disconnect air fitting) before or after each use. But you've also got to make sure that you don't over oil, a few drops is all you need to add at any given time. Over oiling will cause the excess lubricant to be blown out the air tool's exhaust, contaminating the surface you're working on.

For those of us who know that we'll, more often than not, forget to lube our tools daily, there are many types of automatic oilers on the market. These are designed to inject the correct amount of oil into the tool as you work, saving you from having to remember to do it yourself. You can choose between small tool-mounted units or larger capacity ones that can be permanently attached to the garage air supply system. If you choose the permanent air supply oiler assembly, it's important that you make sure it's on a line that's dedicated to your air tools only! You don't want to connect your spray gun to a line that's connected to a permanent oiler.

There are many brands of air tool oil on the market (available at any body supply or tool store), or you can use products like 3-in-1 or Marvel Mystery Oil. Whatever you choose to use, make sure it's a very thin, light lubricant and that you keep all your air-powered sanders and grinders oiled daily!

When it comes to your sanding equipment, there's another thing to remember. Whenever you set down any of your air-powered sanders, always place it so the sanding pad is on its face. Never lay a DA, grinder, or air-board on its side. The weight of a tool laying on the edge of its pad will cause a flat spot or deformation in the pad. If you've got a sanding pad that has a deformed edge, that edge will (depending on the angle of depression) either take more or less material off than the balance of the pad face. This will in turn cause the surface being sanded to become uneven.

Spray Gun Setup And Technique
Since you're going to need paint and material for both your practice sessions, and what we're hoping is your first successful paintjob, I just have to take the time to clue you in to what I think is some pretty exciting news. It's exciting because in this day and age, saving a big chunk of cold, hard cash is paramount-and recently Summit Racing Equipment has introduced a line of high-quality, affordable urethane paint, catalysts, reducers, and associated primers, sealers, and solvents.

Recently, I purchased the paint and materials for my wife's hot rod from Summit and was floored by the savings over equivalent materials from the local paint and body jobber. Take a second and look at the following comparison-keeping in mind that the Summit Racing Paint and Refinishing System products are every bit as good-or even better in performance and quality than what I normally use (a big name brand that I hesitate to name for fear of pissin' somebody off).
