But you have to know what materials to use and the expertise to do it. I had the same damage to my DD and got it fixed with some other stuff on the car. Again I do some work on things myself, but now do not have an air compressor large enough to paint.
I knew that I needed a pro to do it right. He made it look new again.
You might try and find a bodyman who works on the side to do it cheaper. But to do it yourself you have to know what you are doing.
