hold the gun about 12-14 inches away from a test panel . It should look like a football pattern. If it's a figure 8 you are using too much air pressure, back it off until it is a football pattern. If it is small on top and large on bottom.. like a gourd there's dried material in the nozzle where the needle comes through.
Silver and gold are difficult to spray because they have VERY little pigment in the them. Mostly aluminum flake and binder. What happens when you spray these two colors the air pressure will separate the binder from the metallic. Most of the time it's a good idea to reduce the air pressure and do a final "drop coat" where the material will land uniformly and allow the metallic to land with the binder at all kind of different angles to reflect light rather that "plastering them to the car with high air pressure and little binder. You should use a tack cloth "lightly" between base coats to remove the over spray, if you do not it will not allow the other coats to stick and you can expect not so good news next time you go to the car wash. It will peel.
