If I show you a picture of a car that is supposedly "unrestored" you can easily claim that the color was changed like this one. http://www.carsolina.com/ss3.htm
What indisputable evidence would be required to have proof of something like this? I do not claim to know. I am just putting forth literature on the issue, which is what this forum is for, correct?
