I hope you consider Brent's advice carefully because that man's advice comes straight from the bodyshop floor. I can tell, having worked in the trade, that Brent has a pretty good grip on the reality of restoring a car and the real costs involved.
A few things I could add if you're still open to different perspectives...
As much as I want youngsters to learn about preserving & caring for old cars, I would want to be certain the supervisor has actual restoration qualifications and not just someone who went to school to learn how to teach.
Then there's the question if he can control all them kids as they pound away at your car? What if it gets damaged at the shop? Parts can go missing. Will you be OK if the odd original bolt gets lost? Is it OK if the undercarriage gets overspray all over? Have you seen what happens to glass when bodyshops run an airsander into it? Or welding & grinding splatter pitting of the glass? I have seen DOZENS of windows damaged at bodyshops.
Make sure whatever shop you end up chosing, to bring along clean heavy blankets to protect the interior.
Are you going to specify an experienced painter will at least do the final paint job? Or will you be OK with a certain amount of runs, sags & dirt nubs in the paint? If they completely mess up and need more paint, can you guess where the money's coming from?
We must keep in mind these kids are learning....
Have you asked your broker if they will insure the car while in the care & custody of the school system?
If the car is unfinished at the end of the semester, can you be certain the next group of children will know how to assemble it? Will the same teacher be there?
Quite frankly the thought of taking such a chance with any classic is out of the question in my mind. I wouldn't do it and I believe the car deserves better treatment.
If you take it to an individual person for a paint job at least he can answer to what has been done.
My best advice to get your car painted comes down to two points.
1) talk with people who have actually had a classic car repainted in your area, look at their paintjobs, then try and find someone local who does the caliber of work you desire.
2) if you find someone you trust, get a detailed estimate, establish a firm finishing date and above all else
....give them a Bare Minimum of money up front.
It's enough that they have your car...don't get caught in the classic bodyshop trap of "he has almost all the money and the car is only 25% done" or "now he's starting on someone else's car & mine's pushed into the corner"
Bodywork can be a dirty, dusty & discouraging job and if the only incentive your man has is a nice chunk of change....well that could be the best thing for all parties...
Good luck!
