I was using oracals 5600 reflective series for police cars for years. I was finding after 2 or 3 years vinyl turning black especially on 1 side. Anyone have this issue?? Seems to be the Sun since is bad on 1 side. They park there vehicles same direction every day. I have switched over to 3M and havent seen this issue yet. I just got a vehicle back after 6 years that entire passenger side needs to be redone. What is your warranty?? i have been replacing stuff for free here and there, but this is a much larger area to replace for free.
