Never heard of waxing a car before installing OC 2.0. Surface must be free of wax to have OC to adhere. Don't walk to another detailer- RUN ! Go to the Optimum forum and you will find all the info you need to make a informed decision . They also have a listing of all dealers authorized to install OPT-PRO.
