I suggest to the OP and others to give Jerry Nelson a call at Nelson Hobby Specialties, http://www.nelsonhobby.com/

He's a great guy and experienced in both full size aircraft and RC products. I've used his paints with great success and he sells his own brand of iron on fabric.

Fabric and paint is actually easier in a lot of ways than covering with that devil monokote lol. If you don't mind sanding, you'll love the results of fabric and paint.

Edited to add:

Information about his paint is here. http://www.nelsonhobby.com/paint.html
