8. To shoot the clear, we switched the gun tip to a smaller 1.5 tip because the 1.8 that we used for the color would have caused runs. The basecoat didn't need to go on thick to get a smooth look, but the clearcoat did. Be careful; a clearcoat that is too thick means more work with a buffer and compound. You have to learn the balance between spraying too thin a clearcoat and too thick to avoid a bunch of runs.
