The first time I waxed with Adams, I put two coats on the hood. I've also touched up the nose a couple of times. I use detail spray on the applicator, then another cleaning pass with detail spray after I finish the car.
I "layer" Adams but it is not necessary. I start out with a mixture of revive wax and swirl and haze remover for use with my porter cable ( to remove the fine dust scratches ) .... I follow it up with a coat of buttery wax ( applied by hand) ... and finally a coat of brillant spray glaze (applied by hand).... total time about 1 hour.
P.S. Detail spray for touch-ups between waxes
Here is a couple of photos highlighting my results ( I have never tried Zanio)
