How to Use a Car Paint Spray Gun Properly

January 27, 2012

A car paint spray gun is one of the most professional items that you are ever likely to need to use on your car. These guns are normally very expensive, but you may be lucky enough to find one available to rent from a local store or shop. If you are considering repainting your car, then using a spray gun can certainly help you to get the most for your money, and allow you to perform a quick paint job on your car without needing to spend a lot of time fiddling about with spray cans. A paint gun will help you to get the best from your project, but you will need to know how to use the gun before you can begin.

Materials Needed

  • Spray Gun
  • Paint
  • Newspaper
  • Painters Tape
  • Gas Mask
  • Safety Gloves and Goggles

Step 1 - Know Your Spray Gun

Before you begin, you will need to know what kind of spray gun you are using. Many traditional spray guns are being replaced by High Pressure Low Volume guns, as these are more environmentally sound. If you are renting, then you may have a traditional type of gun, with a traditional nozzle set. These nozzles contain an air cap, a fluid tip, and most importantly, a paint needle. These needles mean that you can push out small droplets of paint onto the surface of your car, usually at tremendously high speeds. You should be aware of what your spray gun is doing before you proceed.

Step 2 - Fill Your Spray Gun

Once you are familiar with all the parts of the gun, you can proceed to fill it with the paint you want to use on the car. Most spray gun paints come in an aerosol spray can, and all you will have to do is to slot the can into the appropriate hole in your gun, and the mechanism will do everything else. More complicated spray guns may expect you to empty the paint into the gun before you can use it, so read the instructions on the gun carefully.

Step 3 - Paint Your Car

When the paint is in the gun, you are ready to paint the car. Before you proceed, put on your safety glasses and goggles, and cover any metal decoration with painters tape. You should also tape newspaper over the windows, in order to prevent paint from splashing onto these. Take up your spray gun, and hold the nozzle around eight to ten inches from the car. Press the button, and move the gun in a left to right motion to spray the car.

Step 4 - Finishing

Continue to spray the car until all parts are covered, and then leave to dry. Once the car is completely dry, you should remove all of the painters tape and the newspaper from the car. Check there are no missed areas of paint, and then put the spray gun away until the next time you need to spray paint your car.
