In this age of YouTube, there are useful tutorials on how to achieve a nice gloss finish for a car body. Just light dusting coats, going over the whole car, making sure to get the underside as that is often overlooked. At first it is tacky, just wait a few moments for it to air dry, then slowly build it up with misting coats until the shine comes. If you try to speed it up because you're a spaz (like I am), then you will deal with overspray that will droop and cover up panel lines, etc.
