Polyspan application
I've used Polyspan to cover several models, quite happily. I've noticed several statements of concern over how to get the stuff to go 'round corners, like wingtips. I've had excellent results from treating it like a plastic heat-shrink covering, i.e., get out the covering iron and tug and heat until it works around the corner, and it will, I think easier than the plastic film will. This all depends on having a heavily-doped wood structure so that the adhesive will bind with the Polyspan after all the stretching is finished.
