laminated

I checked on my 2012 V6 that only the windshield and front door wide windows have laminated glass (an ear logo). On a KDM forum, it seems that both front and rear doors are equipped with the same laminated glass. Can any 08-11 or 12 V8/R Spec owners confirm this? If my observations are right...

On my past cars, I used a razor blade to clean my windshields... Pretty effective to get the glue left behind from old stickers/toll tags/etc. Any idea if this is safe to do on the interior of the genesis windshield? I read that the windows are laminated for sound dampening, and I'm wondering...
