Re: after paint...when to wax question?
90 days for any wax that will seal.
You can use breathable glaze like 3M hand glaze.
You can keep it clean with a product like meguires "final inspection".
I like to polish it again after 90 days and then seal it with wax or a sealing polish.
Let me know if you need more specific info.
I am an ASE master painter. Trust me...
