I was talking to a friend yesterday who had just finished wet sanding and polishing a Falcon for a buddy. The guy had spent several months getting everything straight, and then filling & sanding to perfection. They hauled it to a local truck shop on a weekend where one of the guys had permission to use the paint booth. He said that the guy spent $3,800 in materials - filler, tape, masking paper, sand paper, primer and paint. That's just materials, no labor as his friends donated their time to pay back old favors.
