I have customers who understand the time and money required to do the job right. I've also had one that was trying to save a buck and had the car finished and painted elsewhere after I did the all metal replacement and modifications for fit and gapping. The car then got shipped back to me and I had to repaint parts of it that were done poorly by the other shop. Unfortunately the entire car should be reshot but he cannot afford it. Save a nickel, waste a dollar.
Documenting a build with photos is standard procedure for some. Owners two or more states away can't pop in and they are provided progress photos of the build. I do the same with in or out of state jobs for reasons previously mentioned by X33RS. And if the owner ever sells their car, the buyer can see the build from bare metal to paint.
I know of a shop that bangs out cars to sell at Barret Jackson. Cave and pave jobs. The owner told a customer there was more filler in one fender than in an entire car. But it's B.J. so it must be a quality.
