I would be surprised if the film sticks to a waxed surface.If the paint flakes off that easy, if you cover it with film, more than likely it will pull the paint off when its time to replace the film(usually about 5-6 years for a daily driver). Suntek film has the least aggressive adhesive so it would be less likely to pull paint than film with a more aggressive adhesive like Xpels' If you do go with PPF, I'd make sure you have a good heavy coat of wax applied first. That will make removal less stressful on the paint
