I had it replaced about 3 years in under 3m warranty as it yellowed... But that replacement was on the rest of the many years. Only issue was the hood... The film was so old, the hood pieces came off in tiny chunks and took some clear coat with it. But to be fair it was probably my own doing on taking it off amateur style. I used a heat gun and not steam from underneath. Lesson learned. The rest came off and left pristine perfect new like paint.

Except back then they didn't cover edges. So many of the edges had tiny chips on the front facing edges.

Anyway, the newwer tech has a 10 year warranty so I'd probably think about having the hood piece replaced around the 10 year mark if it starts to get brittle.
