I did about 40 miles on my car before sending it to paint. That was 2 miles at a time. But I found out a few things and made some adjustments. I was suprised that I never ran across a trooper. I thought that it was better to sort most things out and not have to wrench too much on the car after the paint job. I was chekcing the guages to see that everything was working and the temeratures were where they were supposed to be. Also got it on the lift after every run to look for leaks. I am still concerned about the first real cruise. Trust me I am not a supporter of driving without the proper papers but I felt like I had no choice and just took a chance. Probably not the smartest thing I ever did but...
