The best benefit that I can now see is that when we install our car-top carrier for family trips, the antenna will not dictate where the carrier has to be placed. It can now be positioned farther to the rear, helping wind resistance and gas milage.
The most important thing about this project is the method of production. As I said, as far as I know, this is the first time Sugru has been "turned." I think this could lead to some pretty awesome things being made with the product (as if that's not already happening).
