Yup - pick up a heat gun from Harbor Freight for $10. When heating use a circular motion and keep the gun moving. It will tighten up tighter than Dick's hat band!
Its pretty remarkable how much you can shrink it up using the gun. Be careful though, if you get it too hot it will soften the material surface and make a shiny spot. Most of the shrinking happens during heating but I saw wrinkles continue to fade during the cooling off cycle
Good luck!
