I have always wondered about it and if it will cure over the wax. I know the WG 3.0 spritz sealant isn't major hard sealant. I have been looking at applying the sealant then the wax 12 hours later. This car isn't driven in any inclement weather and will be sitting another 3 months. I plan on going back to lay another coat of sealer on it, in which I will then apply the wax over the sealer. I have read both ways do work, (but also read many things wrong on the internet) but I haven't played a ton with sealers as most of the cars I do want me back monthly. The next time I visit this car I will do the sealant then wax to test it out. This is one of those cars that don't move ever, but wants it cleaned monthly.
I am also currently working on a full correction on my car that is stored and will try both ways as well.
