I would check online to sites such as autobody101 or similar blogs that you can glean information from people that are in the trade. I wouldn't jump into it head first unless you have a sense of direction. It always helps to have a friend, or family member that has experience doing bodywork.
I believe there are even books that can give you some direction. Another thought...check out your local community college to see if they offer courses in autobody repair. I think that would get my vote.
In either case, you have to start somewhere.
Thank you very much for all this information, Sir. I will check out my local college and on the weekend I'll ask some of the folks and the car show..
