Mark, this advice may be too late for you, but I pass it along to others who are preparing to paint their cars.
Before I took my car to the body shop a couple of weeks ago, I wrote all over it with grease pencil, (china marker). I circled every detail including "the eyebrows",(nicer term than notches)and wrote what I wanted done right on the car. I also provided a printed page with the details listed and walked around the car with the shop manager. We discussed every thing on the list and where that was on the car. I left a copy of the list with him, and one in the interior. He really appreciated the detailed information.
They aren't finished yet, but I took every precaution I could. No matter how good the craftsmen, you can't count on them to be Concours judges or mind readers.
Everyone here is correct. Now is the time to get it right.
