Well I discovered I had a "perfect" cut line in my rear left passenger tinting about a month ago and I didn't really bother with it. I wasn't sure where it came from but I guessed that some dirt or jagged rock or something fell into the window and while the window was being rolled down completely, it scratched the perfect line...

So when I had time, I called up my tinter and had him look at it. The guy wasn't there but his partner was... so the partner explained to me how most car manufactures put felt and plastic to protect the windows and normally both plastic and felt are on both sides (interior and exterior) of the windows. However, the e90 was slightly different in that the front had double sided felt and plastic, but the rear roll down windows only had a single sided felt in the interior and plastic on both sides. He believed that this was BMW saving a few bucks because supposedly rear passengers never roll down their windows anyway. The function of the felt I guess is to prevent the small jagged objects like rocks and sand or whatever from entering the window area...

So to conclude... I'm going to remove + retint the rear left passenger window and also install some custom felt lines to help prevent this from happening again. Of course, the tinter informed me that this would not completely protect my windows and tinting... and problems could always occur... but I'm going with it anyways. Since I'm pretty familiar with the tinter, he said he'd do it for 70bucks for retint & the felt lines or 60bucks for just the retint...

my rear windows have scratches on them too....just like how you explained.

at first....i thought it might be cheap tint.....

but all my other cars were tinted at the same place....and no scratches!

That makes sense. I have a perfect vertical scratch on my R/F window tint..

If you read it says its just on the rear...you have a different problem because the front has felt on both sides

well it could happen in the front... but its more likely to happen in the rear... i suppose it really depends on where you live as well. i live next to dusty train tracks for the school year so crap like that goes on my car all the time.

imho if your really concerned with it from the inside, retint it... but it could always happen again which means dishing out another 60-70 bucks or whatever you and your tinter arrange... & if your not concerned... why bother... most people wont notice the line until they sit inside or are pointed in the right direction.

wow turns out my right rear passenger window has a few fine lines too... not as crisp... son of a bitch... bmw D:

every E90 at our mini meet a couple of weeks ago had the same problem......

[just4kickz]

f'real... how bad were theirs? & were they like omfg fuck this... it's pretty amazing how BMW doesn't want to put a cheap felt strip on the rear windows...
