To Trim or Not To Trim?
"Some wrappers do not cut back their perforated window vinyl from the rubber seals but 3M highly recommends it. What I have personally witnessed is that a lot of window seals seem to "slowly ooze out" an unseen liquid that will make the edges of the perf come up over time. You can help prevent this problem by cleaning the window near these seals with Rapid Prep and/or alcohol and also using the Perfect Tool to "cut back" the window perf."
