Prolly need a good flaxible want to reach the very center of your back
If I were you Nate I'd try to buddy up with a local small time painter and just ask if you can watch and learn...or better yet, ask if theres anything you can do to help with his jobs to see what goes into painting
That is....if you really wanna learn
My buddy here at the office has a brother that runs the paint shop at the local community college and painted my parts one saturday for just the cost of the paint. I got to watch the whole process and learned a great deal. Plus is only cost me $75 to have my WHOLE bike painted
