I just went through my first semester at a technical school in Kentuck for Auto Body. I was amazed my first days that people would actually allow students to lay paint on the cars. To my surprise the cars came out looking brand new. The paint jobs were not free though. The customer had to buy the paint and add 8% of the cost on for labor. It is very cheap in the end though. I would just speak with the instructor and make sure he/she sounds trustworthy. He/She will be the one monitoring the project to make sure it goes smooth.
