I've since spoken with LowBoost via phone. My car is also full wrapped in Xpel Ultimate. You take care of the film as you would your paint. It has an automotive clear coat on it so you can wax it etc. IMP: C-Quartz, Modesta or Opticoat (ceramic coatings) should always be applied on top of the film.
Phidailo, Xpel will warranty that film for you where the rock chips have penetrated the film. Any questions shoot me a PM.
