you can apply pure carnauba wax kahit na every week po after the Optiguard sessions. Just stay away from cleaner wax since it will just strip away the sealant.

maybe what our detailer meant was sayang naman if you will wax it agad after the Optiguard sesssions, but it also depends on a lot of factors like where you park your car, exposure to UV rays or acid rain, etc. There's no harm in waxing often though as long as you stay away from cleaner waxes and the likes since our Optiguard sessions will handle it.
