I faced the same issue when I got ready to paint my 37. After reading and talking to numerous people I went with the single stage. Absolutely no regrets. This was my first auto paint job and it turned out super. One of the most reliable information sources I had was the owner operator of a local top end body shop. In our area, this is the shop you go to if you want the best of the very best auto body work. He said single stage. I also used the paint manufacturers web site to get all the tech sheets for their products and followed there instructions completely. I used Dupont. I haven't had to repair any paint/body stuff yet, but ease of repair and excellent finish are both good reasons to go single stage. Ralph
