The fastest cars look like a wedge, with the front narrow. If you or someone who will help you is very good at cutting wood, you can do something fancy (like a hot dog or a car with windows. ) If its your first time, you may want to do something simple.

Many thin coats are better than 1 thick coat, as it has less chance to run or drip and spoil the looks of the car. Let the car dry between coats, and sand after the paint has dried. The final sanding should use 200 grit sandpaper. After sanding, you can attach whatever decals or lettering you might want.
