Things you should know about
1st, you should always have a Lifetime Nationwide Warranty for your tint. If there is a chance you will be moving out of State, make sure you receive a Warranty card. This card will provide you proof of purchase, the type of window tint used and the roll numbers of the tint used.
2nd, use NON-Ammonia based cleaners. Window tint is porous and ammonia can travel through the tint and eat away the adhesive.
3rd, your window tint will appear a bit streaky for a while and may even have a water blister here and there for the first 24 hours. This part of the normal drying process. It can even take a few days depending on weather temperatures.
