Hey there,
Glad to see ya here at DC...Welcome!
I would think that waxing over the clearcoat would help protect it.
Since the clearcoat isn't very thick...it would need to be protected.
I see an awful lot of neglected paint on vehicles that I detail...and I think "If only they would have took better care of their paint".
IMO, a vehicle needs to have some kind of protection, whether it is a wax or a sealant.
