Don't half step on it or you will just be doing it over next year. The quality of tint that they use is huge. You have to ask them what they are using. The material is very important and so is the person laying it. Don't get a 100 fly by night tint. You will just be scraping it off later on and doing the same thing all over and spending more money. I would say that the quote you got is from some top quality tint and I would bet there is a warranty with it. The real good stuff, like 3M and titanium grade tint is expensive and will come with a life time warranty. The golden rules apply here for sure, "You Get What You Pay For", LOL. Sorry, had to say it. Are they a reputable dealer that has been there for some time or they set up in a tent on the side of the road and move from week to week?
