Actually I had planned on doing that, but not with the Lexus. A lady cop brought her 93' Integra to get it repainted. It's only in the beginning stages, but the rear bumper was taken off. The guy showed me how much rust they found afterwards. Anyways, it takes them about a week or so to complete a car. Once they finish that car, I will drop by and see the end result. I think I will have a better idea of how good of a job they would do on an older car with existing rust.
BTW, the shop owner bought a 2002 BMW (I think it's a 5 series) from an auction. The front end was crushed. He bought the car for $23K and fixed the front end and repainted the entire car. I did see it and it looks great. Unfortunately the day that I went there, his car was hit behind the driver side door. He showed me the dent and none of his paint came off. It was smashed in good and only had the woman's car paint on it. So, he told me that's how good of a paint job they do, when someone smashes into you and your paint does not come off.
I'm new at all this, but I tend to believe that. Is there any truth to that?
