I cant remember, but asked at some point and I remember it being top notch. If you need I can give you their number. They will let you know for sure. I have never had any issues except one driver window had a bubble and they replaced the film with no questions!! Mind you that between myself, friends, and family.........I have had between 25-35 cars done there. My brother used to go to Ziebart, but always overpayed and had to always have windows redone. No, you dont have to drop it off. Just call and make an appt. I usually set an appt for Saturday morning at opening, and I am out of there within 1.5-2.0 hours. I usually walk across the street and grab a coffee and donuts from the speedway, and I usually bring some good car mags to read. Its pretty quick, and a job well done.
