Hi James,
We have been using the *Truck, Van, and SUV* big cans of Duplicolor lacquer for several years. I have found them to cover a bit better than dope, usually. Now I am experimenting with the *Paint Shop* quart cans and spraying them on. That way I can add a *little* flexative and fish eye killer to it. I shoot urethane 2 part clear over it, and it has held up excellently. I haven't found a *down side* yet! The Paint Shop colors are very limited right now, but they have added a *Metallic Clear* and a *Prism Clear* to use between the color and top coats. There are 8, IIRC, colors right now, but you can easily mix any color you want! I have a feeling that a stunter will get the *Prism Clear* before too long!
