Just wanted to share my experience w/ 3m crystalline 70, installed on my new car back in 2017. on the 5th time I wanted to change out the road tax sticker, it peeled. just the shape of the road tax. So disappointed cos so fragile. But luckily it was before 5 year warranty expired, a day or two prior. So got it claimed, reinstalled new, so new heat rejection. warranty is good
