Scuff for paint. Once your Mustang is totally stripped of exterior chrome it's time to scuff up the existing paint. The paint shop should do this also, but on the lower end paint packages they won't spend much time here. It's better for you to do it so you know it's done thoroughly.
Primitivist (naive) artists depicted objects in a solid monumental manner, as seen by a child who perceives the world as a whole, without analyzing it and breaking into unnecessary components.
First consider the size of the painting. The more impressive the subject, the higher the emotions it appeals to, the bigger it is. Religious, mythological paintings are often huge - their massive energy makes you shiver. It is pretty understandable with figurative paintings like Rafael's "The Sistine Madonna", and more subtle with color field paintings of Mark Rothko. People are often overwhelmed with religious tremor in the presence of his artwork, and the size factors in. Also, the subject often calls for larger canvases - battle scenes need space and cannot be fitted into a smaller painting, while some subjects will get lost unless depicted in a smaller size.
Even if you don't need to apply a coat of primer before your new coats of paint, doing so will always save you money. Whether you use white or tinted primer, a coat of primer is always more cost effective for one simple reason: It is cheaper! In fact, primer may cost as little as half as much as standard paint. If you get it tinted the same as your paint, then it is cheaper by the coat. If you use white, as in the first scenario above, it will also minimize the number of coats of paint you have to apply. Either way it reduces how much paint you have to buy. Do you want to learn more about maximizing your paint color coverage, minimizing your paint usage, optimizing coats, and perfecting your primer?

Now that you have primed the airless, make sure that there isn't a tip in the gun of the airless and bring it over to the empty bucket. Since there is typically cleaning solution in the hose leading to the gun it is a good idea to spray that out until you see thick paint coming out. Once you have thick paint coming out you may put your tip back in. Remember that the tip will have an arrow on one side of the handle that shows which direction it must be in, in order to spray.
