Hi, sorry if this is resurrecting an old thread but I found the information and photos relevant in my search of purchasing a retractable bed cover for our F-150 (ex: Roll-n-Lock). I've been trying to figure out if a vinyl-covered aluminum top can be protected for years or if I need to go with the powder coated aluminum tops. Do you still have the truck that this demonstration was performed on? I would love to see how it looks after years of use and UV exposure. Thanks!
