When you pick up a spray gun, then you have a completely logical question: how to hold it correctly? The spray gun should be exactly 90 degrees to the surface to be painted. The main thing is to observe this position when painting large parts. Ignoring this rule is dangerous for the appearance of areas of different shades on the surface, especially when using metallic paint. You can tilt the spray gun only when painting ends, arches, and various hard-to-reach places.
Distance to the painted surface
The most optimal distance from the painted surface of the spray gun to the spray gun is considered to be 15-20 cm. For clarity, you can use the width of the palm with spread fingers, on the hand of an average person it is 19-21 cm. This can help you estimate the distance. Also, the distance may vary slightly depending on spray settings, viscosity and paint type. If the distance is too small, then the so-called "orange peel" effect is possible, smudges are also possible. If the distance is too large, then the paint will dry out even in flight, forming a large spray, as a result of the "dry" coating and high paint consumption.
Spray gun trajectory
Coloring should be done from left to right, in horizontal movements. The spray gun must be guided evenly, without changing the speed, in the most parallel movements. Do not forget about the correct position of the spray gun !!! Each new passage must follow the previous one at least half. This will avoid streaks in the paint.
So, start moving away from the upper left edge of the surface and immediately pull the trigger completely. Having reached the right edge, without stopping the movement, release the trigger. The main factor in mastering painting is determining when the trigger is pulled. But, as practice shows, over time, control over the trigger is triggered reflexively.
Painting the ends and internal parts of the part
There are several rules to apply to painting the ends and internal parts of a part, for example, painting the front left fender. First, paint over the ends, starting from the top at the bolt attachment point, go to the front, at the headlight attachment point, then the wheel arches and lower ends, and at the end, the side end near the door. Well, now we paint the front part of the wing. This sequence will prevent dusting on the face of the painted part. In general, when painting any part, the ends are first painted, and after the front part, then the spray on the front part is excluded.
How to paint wide (long) surfaces
Long surfaces are more convenient and easier to paint in parts of 60-80 cm. The parts to be painted should overlap each other by 10-15 cm. Painting such surfaces entirely at one time is fraught with uneven application of paintwork.
How to paint the horizontal parts
Horizontal parts (hood, roof, trunk lid) should be painted in the same way as the rest of the parts, but you need to start moving from yourself and gradually move forward. It is also allowed to tilt the spray gun towards yourself (the torch away from you). Thus, each pass will overlap the dust remaining from the previous pass.
Full car painting
I usually start the full painting of the car from the roof. If the roof is painted last, then dust can spoil all other parts, since they are located below. It is unlikely that a spray on the roof when painting the lower parts is, and if it does, it will not be noticeable as on other parts. When you pick up a spray gun, then you have a completely logical question: how to hold it correctly? The spray gun should be exactly 90 degrees to the surface to be painted. The main thing is to observe this position when painting large parts. Ignoring this rule is dangerous for the appearance of areas of different shades on the surface, especially when using metallic paint.
