Best way to avoid runs is to spray a very light mist coat first, let it dry until tacky then add your first full coat & apply every other coat when the last one is still tacky. This gives each new coat something to stick to & helps avoid runs.
To save you sticking you finger in your panel to check tackiness spray a piece of scrap wood just before you start!
It also lets you check if your spray pattern is correct.
