Unless the wax has cleaning agents in it, there shouldn't be any bonding issues, as wax doesn't really bond, it layers. Sealants are more bonding types than waxes, so make sure what you have is actually a wax and not a sealant, and that there are no cleaning agents in them.
Dawn washes help, but you can also IPA wipe the paint, and use an AIO to remove anything beneath it also, then wax on top of the AIO. It really depends what you are using and if it's a wax or a sealant and if it has cleaning abilities.
