The tint installer obviously did'nt explain things at all. Like I said earlier the cloudiness is normal. It's actually water that has to dry out between the film & the glass. It should go away in about a week or so. If for some unknown reason it doesn't then take it back & have them re-do it. Any tint installer worth a damn will almost always give a warranty. The guy that has done the majority of my vehicles gives a lifetime warranty against cracking peeling & bubbles & haze. Just relax it'll be fine in a few days.
