What is the shelf life of GTMAT?

GTMAT may be stored at temperatures of 50 degrees Fahrenheit to 90 degrees Fahrenheit for up to 1 year before use.


May GTMAT be applied in cold temperatures?

Yes, GTMAT may be applied in cold temperatures but for best results applying heat with heat gun or hair dryer to either material or body of vehicle will help with adhesion. This will also allow for product to stretch to reach smaller creases and crevices. Keeping the material stored in recommend room temperature will also help with pliability and ease of installation.
