back on topic...Mooniteman, if you haven't looked into it, Shell Shock® Brushable Liquid Plastic | Smooth-On, Inc.
my concern...resins are only as strong as the material they are put on, ie glass cloth, kevlar. since the foam is pliable, would it crack if hit? I read a few first hand accounts of people using the product and it didn't like extreme cold. the good thing is the guys at Smooth-on are extremely knowledgeable and can answer all your questions.
