Here's an easy way to do graphics on your car.
1. Tape off the area with wide masking tape.
2. Draw out your graphic and cut out with a razor blade.
3. Paint it layering colors for a better effect. Mask off wider with newspaper to prevent over spray.
4. Remove the tape after the paint dries. Beautiful!!!!!!
5. Save the numbers you cut out and lay over you tape job on the other side. Then just trim around them with a razor. When your done a paint marker will fix the screw ups.
