Robnewman,
Personally, I prefer fiberglass cloth and paint. This process provides a very realistic looking surface and adds a lot of strength to the aircraft. There are lots of videos available at your LHS and On Line on "How To Fiberglass". Check out my thread "C-47 Normandy Tribute June 6, 1944" here on RCU. She is covered with .75 oz. fiberglass cloth and painted with automotive paint. You can also see a couple of my planes in my gallery her on RCU. Good luck.
