Most waxes are paint sealants and like mentioned BC/CC does not need it .
PPG says 3-4 months air dry before any type paint sealant is used .
It takes this long for all Solvents and Catalyst to GAS off for a hard finish.
Now if the paint job was cured by infrared 24-48 hours.
I will only use a good quality polish , it does wash off in time so re-application is required .

To me wax is so 1970's , to many other better products out there .
