Installer damaged paint..what would you do?

[Denalio]

Well here is the situation. I had my new e70 at the dealer install 3M clearshield. The installer did a very poor job installing the product, frankly a hack job. I have more seams than a soccerball! There are numerous wrinkles, white marks and work marks all over the front end. So now it has to be re-done by another installer at another shop. Someone that knows what they are doing. I had a couple other installers look at it and they were appauled at the workmanship and the install. Problem is when the original install was done the guy cut the film while it was on the car now the paint is damaged and cut where the original was. This guy was supposed to do a "custom job" and was highly recommended by the dealer. I was going to have it done by another place when the dealer said that they could do the same exact job for the same cost. Now I have to deal with the dealer telling me that they will refund the cost of the original work which is $399.00 and I have to have it re-done at a cost of $500.00. I told the dealer that they will pay for having it re-done and any paint damage will have to be repaired. Unfortunately the only way to repair the cut paint is to have the front all re-painted which I do not want to have done. I am getting resistance for accountability from the dealer. This is factory paint and a $100.000 vehicle that was damaged. I know a new replacement vehicle is extreme, but what would you do? I welcome your input and suggestions.
