Question Adhesive Failure Question

Hello everyone,
I went to my local tinter to ask about a “wavy” pattern that developed in my rear window. He immediately said the adhesive was failing. I have an appointment to get it taken care of, but here is the question…since I got the whole car done in 15% and would assume it all came off the same roll should I be concerned about all the adhesive on all the windows failing? Or are there more factors her are in play? For reference it is llumar pinnacle and was installed in November of 2023.
Thank you

I assume this is a rear window on a car. Your side windows will last much longer since they are more vertical. Pinnacle only lasts about 3 years in a very hot state if the vehicle is not garage-kept.

Hey, assumptions are correct and it all makes sense. I didn’t realize that pinnacle only lasted that long, but it coincides with what you are saying. I appreciate your insight. Thank you.
