Hello all,
Just want to clarify something. With the XPEL ULTIMATE Paint Protection Film, you can use ANY wax/sealant/coating you want on the film as long as it does NOT contain petroleum distillates such as naphtha or kerosene. So you can keep using the same wax you've always used as long as it doesn't contain one of those ingredients. As far as IF you should wax or seal the film at all, well that all depends on your driving habits, where the car is stored, and climate. If it's garage kept, cleaned often, and well taken care of then you shouldn't ever need to wax or seal it. If it's parked in the sun a lot and not cleaned very often then you may want to apply a wax, sealant, or even a ceramic coating to the film. But the same is true for bare paint.
Hope this info helps. Let us know if we can answer any other questions.
