BFCS - Wax - BFCS ??

[mjsjax]

I have searched the forums for an answer to my question but have not had any luck finding a definitive answer. My tentative plan is to apply Blackfire crystal seal followed by 1Z einszett Glanz Wax (after appropriate surface prep, of course.) So my first question is: should I even go with the wax to extend the life of BFCS? And if I do, can I apply BFCS over the wax in a few weeks/months? Or am I creating more work than is necessary (if you can call 11 minutes 'work'). This will be my first time applying a paint sealant and I am not sure what route to take. The paint is in very good shape (boring, lifeless Ibis White on an '08 Audi A6) and I want to try to give it a little extra 'something'. Thanks for your advice - this place is a goldmine for amateur detailers like myself!!
