As Tom said, "Welcome" to Autopia.
Thank you for the very honest review - it's much appreciated. I echo your findings - for me, the shine wasn't any better than a $2 tin of Armor All wax, and the durability appeared to be around 8 weeks (surface stopped beading, and started squeaking when rubbed gently).
The bad news: FSS didn't work as well as you had hoped. The good news: You can play around with some new products - the failure of FSS is a perfect excuse to buy some new stuff to try.
Thanks again, and good luck with your future details!
