I used blue painters tape to cover the top half of the truck. Notice that the tape along the side is cut in a wavy pattern. While you can purchase masking materials already cut (for flames, waves, etc.) I used materials I happened to have on hand. I applied the tape to a piece of stiff plastic, traced onto the tape with a simple stencil, cut the tape (still on the plastic), then peeled it off the plastic and applied it to the truck.
