Gravity feed
spray guns offer a unique way to paint a vehicle.
When painting a vehicle, one option is to use a spray gun. Spray guns are known for allowing a smooth coat. Gravity feed spray guns are unique in the fact that the paint comes from above the spout. In other words, the paint can or reservoir sits on top of the gun and is fed into the gun by gravity. Using a gravity feed spray gun takes some skill and know-how.
Safety
First of all, using a gravity feed spray gun will be nearly impossible if the user can not breathe. Users need to wear a breathing mask. Inhaling paint fumes can be deadly. Goggles and gloves also add an extra element of protection for the painter.
Vision
Gravity feed spray guns are different from bottom and side feed spray guns because the reservoir is on top of the gun. This offers some unique advantages, for example, the gun needs less air pressure because it relies on gravity. On the other hand, the reservoir being on top of the gun means that the painter must work around the reservoir as it is directly in-line with the spray nozzle and the painter's line of vision. To combat this challenge, a painter might stand or sit in a position that allows her to look at down at an angle over the reservoir.
Stroking
When using a gravity feed spray gun, long smooth strokes work better than short bursts. The longer strokes allow the paint to coat the vehicle more evenly and with a uniform amount of thickness. Filtering the paint before pouring it into the gun's reservoir will help prevent the gun from clogging and splattering paint in unwanted places.
Air Pressure
Gravity feed paint guns require less air pressure than other types of paint guns. Start with less air pressure and gradually increase it to gauge the results. A painter can always add more pressure to achieve a richer deeper look. Before using the paint gun on a car, test the pressure and results on a piece of cardboard or, if possible, a piece of scrap metal. This will provide a more accurate sample of how the paint gun will perform with the chosen amount of air pressure.
