Wear and tear can really dull an interior so we have car wash products that can bring it back to new. “Foursquare” is the best word to use in describing how a spray gun should be held relative to the surface that you are currently painting – any deviation of angle is likely to cause faults in the finished paint, possible ones that are large enough to merit stripping and starting over again. Although the human hand is not an absolutely precise instrument, and spray gun techniques are robust enough to accept a little “wobble” in the angle, you should try to maintain correct positioning as accurately as possible throughout the paint job.

Generally speaking, a painter cannot go wrong by laying down each stroke of car paint with half of its width overlapping onto the stroke immediately before it. This ensures that there is an even, thorough coverage, with excellent blending between the strokes so that there will not be horizontal stripes visible on the car’s surface like those found on a childhood magic marker drawing.

A complex combination of air pressure, paint viscosity, surface preparation, painting speed, positioning of the spray gun relative to the surface, and the painter’s gait and steadiness of hand are all involved in producing a smooth, even, glistening paint job when the car is finally rolled triumphantly out of the garage or spray booth. However, all these other factors are rendered completely null and void if one particular detail is not attended to – the need to overlap your strokes.

Even if you have no problems with your spray pattern – such as a bulging center-heavy pattern, the peanut shape of a split pattern, or the cashew-like curve of a blocked wing port – then you will need to adjust the width of the pattern to match the materials you are using and the job you are undertaking.

Since drenching the exterior of a car in a single, simultaneous, smoothly even coat of paint is impossible, it is necessary to paint a vehicle in swathes several inches wide, known technically as strokes. Strokes can be made either horizontally or vertically – horizontal strokes are much more common, and are used for most painting situations, but there are some occasions when a vertical stroke is necessary. The spray gun must be adjusted to each of these situations, which is fortunately a fairly simple operation.

However, there are some painting experts who argue eloquently in favor of using a second spray gun for nothing but primer – and, as with their opponents who hold that “primer guns” are an unnecessary expense, they base their argument on the considerable expense of a new spray gun.

The cost of a good spray gun is not negligible – at around $350 to $400 apiece, they cost as much as lower end personal or notebook computers – so the question naturally arises whether it is necessary to buy a spray gun for primers and another for paint and finishes.

Although some solvent may be too badly contaminated by paint to be used again – depending on the type of paint involved and other considerations. However, much solvent can be salvaged, especially after the initial cleaning spray through the system – the following rinses, though essential, are likely to be far less tainted than the first load of solvent, and even if that needs to be disposed of. You will not want to use this “recovered” solvent for any other purpose than cleaning in the future, however.

Since a spray gun needs to be cleaned after every use – sometimes within a half-hour or slightly less, if permanent crosslinking between paint remnants and catalyst will occur within that time, causing an immovable plug that no amount of solvent or soaking will remove – it soon becomes clear to anyone who makes regular use of a spray gun in car painting that a lot of solvent is going to be used in the cleanup process. The amount of solvent needed is increased by the fact that much of the troubleshooting needed for a spray gun involves cleaning different parts.

Some materials problems are even more serious than those which were just described; these hindrances can prevent the paint gun from working at all until they are addressed, or cause such huge flaws in the paint application that the spray gun might as well be non-functional.

The other “family” of problems with a spray gun involves the materials being sprayed – primer, paint, clear coat, and so on – rather than the air supply itself. There are more of these problems than air system faults that a painter may need to contend with, and solving them is generally more complex because of the multiple possible causes for each specific difficulty.

The hiss of escaping air is not a sound any painter wants to hear when they do not have their fingers on the trigger of their spray gun. That slight, sinister noise indicates that something is seriously amiss with the device, which must be rectified if the implement is to work properly. After all, strong, steady, predictable air pressure is the foundation of spray gun operation, so unpredictable variations in the air pressure – or loss of air pressure – can seriously harm performance and the quality of the finished paint.

A well cared for spray gun can last for many decades, even a lifetime – after all, it is not subjected to high stresses like a hammer, a saw, or any angle grinder, and spraying paint is involves little sharp contact with other surfaces and no pressure or strain.

If your spray pattern test is conducted and shows a correct, even, elongated oval without excessively pointy or ends or a noticeably bulging center, then all is well and you do not need to clean or adjust your spray equipment. However, any deviation from this “ideal” pattern requires you to work at bringing the spray pattern closer to the necessary benchmark, as follows --

Although handwriting analysis frequently fails to yield any useful results when applied to human beings – with only the most tortured explanations actually matching a person’s handwriting to the supposed personality traits allegedly revealed by this method – examining your spray gun’s “John Hancock” for revelatory information is much more straightforward.

Although ensuring that your workspace has proper ventilation will help to generally increase your safety and produce a better finish on your car, you also need to take care to directly shield your body. This will also protect the work from coming into contact with the natural skin oils of your hands, or the lint and dust from your clothing.

It is often the invisible perils of our world which are the most dangerous – since they are the most difficult to avoid. Many a stout swordsman of the old European warrior-culture was brought low not by the skillfully-wielded weapon of an enemy, but by legions of bacteria lurking unseen in drinking water that was not properly boiled. Many a doughty laborer and leathery explorer have been felled by the microscopically small pathogens in the beak of a mosquito or a flea.

Setting up and using a spray gun involves basic knowledge of how the device works, so that it is possible to judge when it is working correctly, and to determine what kind of air cap and other accessories you need. One thing that you must determine is what air cap is necessary for spraying the type of paint you are planning to use to coat your car.

Paints and all types of paint-related products – including primers, clear coats, and so on – harden eventually, and leaving even fairly limited traces of any of these substances in your spray gun after you have used it is an invitation to reducing your favorite painting implement into a useless and more or less solid lump. Even if the dried paint can eventually be soaked out with solvent, a great amount of time and effort will be wasted performing a cleanup which could have been avoided by clearing the gun out initially immediately after use.

Keeping the spray gun the correct distance from the car’s surface is vital to getting the paint results that are needed for the job. Holding the air cap too close to the panel will result in too thick a layer of paint – which will then sag, run, and create large, raised streaks and channels in the paint’s surface once it dries. Even slightly too thick paint can result in the countless thousands of tiny nubs which make up “orange peel” texture.

With all of the different types of spray gun available on the contemporary market, and the array of strengths and weaknesses that each one displays, it might seem to be a puzzle that only a philosopher could solve to decide which one is best for a beginning painter. Fortunately, the situation is not as bleak as that – and there are recommendations from the painting experts on what kinds of spray gun are best for those starting out in the

Research into all aspects of automotive painting and repair equipment continues steadily, if not always predictably, over time, and the inventors of the high volume low pressure (HVLP) spray gun were not content to rest on their laurels and collect their royalties – or, if they were, others were standing by, reading and eager to take up the banner of spray gun development. The story of spray gun improvements did not end with the development of HVLP – further advances include the creation of Low Volume Low Pressure (LVLP) spray guns as well.

The human mind often exhibits a strange inability to make connections between different physical phenomena that are common in our everyday world. For example, the pull rings used to open sardine tins have existed since the Second World War, if not before, yet it took close to fifty years for anyone to realize that they could be fitted to other types of cans as well, leading to the “invention” of a convenience which could have existed several generations previously.

For many decades – since spray guns were first used to paint cars until very recently, in fact – the only spray guns available were siphon feed spray guns, mounting the paint cup beneath the nozzle and using air pressure to siphon the paint upwards into the paint needle valve, sucking it upwards by using an extremely high pressure – often between 30 psi and 50 psi for the older enamels and lacquers.

As with any precise task that uses a specialized tool for its accomplishment, spray painting of automobiles has developed a terminology of its own to ensure that precise information about how to carry out various painting operations can be transmitted easily from one person another. The absence of a specialized terminology usually has the effective making explanations long-winded and vague, so it pays at this point to memorize a few terms used to describe the different parts of the spray gun and spraying equipment. The vocabulary is mostly straightforward and easy to recall.
