Learn the to use a Paint Gun
Learning how to use a paint gun does not have to be expensive, you can learn how to use a paint gun with a smooth flat panel (ie...white board, the fender on your car, whatever would be flat and smooth)and some water. I was taught how by using water, place water in the paint gun and use it to spray on a flat smooth vertical panel.To adjust the paint pattern use the knobs on the back of the paint gun. One will adjust the spray pattern and one will adjust the amount of product that is sprayed on the panel. Now you can see how the adjustments on the paint gun work by spraying the water on the flat panel. Adjust the paint gun so that you have a wide even spray pattern, the knob that adjusts the amount of product sprayed on the panel can be left wide open. You can adjust how much product by the amount you pull the trigger or the speed that you move. This is learned through trial and error, practice makes perfect. You can start learning how to paint with out wasting paint, by using the water method. When you can spray water on a smooth vertical panel with out the water running you are ready to start trying to paint. When using a paint gun make sure to overlap evenly.When you overlap, overlap about half each time this will make the finished product even. If you do not get the application even you will cause apperance problems including orange peel (paint that looks rough like an orange peel) dry spots, zebra stripping (paint that looks like a zebra) and thin paint.The pattern should be wide and even for proper paint application.
