I have 2x Fuzion for over 6 weeks and it's beading real good. Car is garaged during the work week, but sits outside at nights and on the weekends. BTW I have 9 coats of UPGP under it.
Ask Meghan, she will have a good idea of how long it last. Since it went on her ride,back at DTFIII she will be able to saw how long it lasted. Before she reapplied it.
No clue on the durability, I have a container myself that has practically never been used.
But if you read all the info that Autogeek has on Fuzion, you will see that you can restore the gloss and extend the durability by using Wolfgang Deep Gloss Spritz Sealant regularly, such as after each wash.
