I would check with your painter to see what the paint used is and what they reccomend for a drying/curing time before a wax or sealant should be used.....
some people say a wax can be used after a fresh paint with out interfereing with the outgasing of the paint during cure time...but I never seen any white paper saying so....paint companies like DuPont...Sikkens..3M...BASF ..all say to let the paint cure before waxing it....some have a time period of 30 days and some have 90 days....depends on the paint company and chemicals used as additives in the paint mix....
you can use a glaze weekly like Meg's #7 to keep it looking good till it cures...but its not a lasting product..so needs to be done weekly....
call your painter and see what he says about waxing...he may have used a cure accelerator and your wait time may be short...
