RE: covering how too's
If you want a great looking fabric, use SOLARTEX (from Balsa USA). It's an iron-on, it's already fuel proof, it goes on easily, shrinks up nicely and it LOOKS GREAT! No glue, no balsarite, no dope or adhesive of any kind. It takes any kind of paint or dope for a final finish. As they used to say in commercials years ago, no muss, no fuss, looks great.
