RE: Fabric covering questions
If you use as fabric a 0.005" thick polyester (skirt lining) or a light Ceconite fabric you will not have punctures or tears unless your badluck is hiting a sharp object like the tip of an iron fence or the tip or a dried boken tree branch.
You have a 95% change of having no damage worth talking about particularly if your model is well glued with aliphatic glue and glue fillets have been applied and the finish is gluing every thead of the fabric to the structure.
