It's definitely worth a try. I haven't had any body work done in about 11 years, but I suppose a box of doughnuts and the offer of a free test flight on the trainer wouldn't hurt would it? If a body man were in the mood to do a favor I could see if being simple enough for him. Leave the plane there and just before or after he does a car he shoot a couple of coats on the plane and charges me for the actual paint he uses. Some would consider it an aggravation to do it but I suppose there are a few who would think it was neat to do it.
