Welcome to the forums! Pull up a keyboard and stay a while.
Niggling point, but Future isn't a wax, it's an acrylic floor finish. No need to buff it, like you have to with a wax.
Future is used primarily for gloss coating prior to decaling. Treadheads and wingy thingy guys tend to matte over top of the decaled model prior to weathering. There are reports that some people even use it on floors, but that's not been confirmed.
Everything you wanted to know about Future, care of Swanny.
