HAha. But on a serious note what are the legal ramifications? Can you just tell the county clerk you changed colors? Or must it be re-registered under the new color? Technically you havent changed the color... but in a way you have.

 

Durability can also be an issue.

On the 430 Scuderia we test drove, the film started bubbling and tearing away at the front vents, where the hot hair is blown out from the radiators. That is after a couple hundred miles on the road and one track day in cool weather.
Maybe some executions are more durable, but I would not bet on this as mid term solution. Good enough for a short term prank, but then it becomes an expensive idea.
