In other words, people who have painted keep the spray gun always an equal distance from the surface. Don't swing the gun to produce heavy and light spots. Fact is , the more you do something the better at it you become, unless you are just "born" with experience. I wasn't. if your afraid to spray it but do the prep work, WHICH AGAIN IS THE HARDEST AND MOST IMPORTANT PART, Mako or a qualified shooter is the way to go but if I did all the hard work I would not want someone to get the credit for a great paint job when "SPRAYING THE PAINT IS THE EASIEST PART".
