Don't know the quality of 1JB's old clear-bra installation and what material was it made of, but I have only praises to say about mine (installed in May). People never know I have it until I tell them about it. I think it helps that I minimized the amount of visible edges as much as possible. I covered the whole hood, front bumper and front fenders to where they meet the doors. Only visible are two 3" edges on each side right below the windshield -- as they don't make rolls wide enough to cover the hood in its entirety. Really easy to maintain and clean. Just wash with soap and spray with Plexus. Bugs, dirt, etc wipe off really easy. I can only hope that I'll be as happy with it years from now but no one can tell.
Do follow the break-in procedure religiously. It will be in the manual. I bought mine in May now at 3000+ miles (driving it only on weekends) the car starts to really loosen up. The engine sounds smoother, revs easier. I never crossed 4200 rpms during the first 2000 miles. Crossing it after that was like driving a different, new car. You will LOVE the car.
