I use heavy duty space blankets with sewn edges, foil on one side, ( foil side up in most cases) that I clip on with those heavy duty black paper clips you find in use in offices. I have been in wind, rain, and hail storms and only had one or two clips come off on occasion. PUGS are expensive. I went for the cheaper solution and have had great success.
