to the OP.
as long as you use polymer based sealant you are okay on the wheels.
carnauba waxes dont last very long in high heat.
I use Prima Hydro after every wash to wax my wheels. Just spray,
and wipe down using a soft paper towel. you can get Hydro here:

Hydro lasts over 4wks, so on my car's paint, i use Hydro every other
wash. you can Hydro plastics to dress it, over glass, etc. does not
whiten or smear.
hope it helps.
