is it beneficial to apply wax over Polytrol?

I was desperate to restore the faded gray front cap on my Arctic Fox. So I applied some Polytrol in the hopes it would bring a little improvement to the finish.

It looks very promising but, in spite of some internet research, I can't seem to find out if it would be beneficial to put an overcoat of Meguire's carnauba wax over the Polytrol.

Does any one out there have first hand experience with the Polytrol and wax?
