Oh, and word of warning... In the trunk there is electronics in the cavities behind the wheel arch on both sides. The audio amplifier is on the driver's side, and has holes on the top of the case. 
 
Roughly 50% of bimmerpost form members that got tints installed had the amplifier fail due to water damage. Any water at all from the rear deck drops right onto and into that amplifier!
 
It's pretty easy to remove (one 10mm nut), or you could put a bag over the top of it probably. 

Yes, if you check my first post, I mentioned that I messed up on the doors twice, and though I didn't say why, this was the reason...
 
Please let me know if you have any tips for that. I was planning to remove the tweeter unit and door card to see if it would reduce tension on the seal in the corner. 
 
The other thing I noticed is that the rear end of the seal is lower than the rest of it, so if you trim your bottom edge to have a ~1/8" down inside the seal, the back edge will have a small section of glass exposed. It wouldn't be visible because it would be inside the door shut, but it might catch when the window drops for the door to open because it won't be under the seal the whole time, and as you said, the seal is tight at each end.

Dodge flexfilm and suntek, get some film from express. Classic series black or charcoal or hp. Probably best to order some short rolls of classic black if you're gonna teach yourself.

Classic black is in buytint.com. this forumn is full of people that are direct with their answers we do not sugar coat things because it is easier that way. Thats what makes this place awesome. We are informing you, it might be sarcastic but we are still helping you.

For removal use a steamer or soak film with an ammonia based cleaner such as windex, use trash bag to keep it on the window. Place in sun and check it periodically to see if the film has loosened up from glass. Order white scrub pads like 10 of em cut them down and used the same cleaner to remove adhesive. (Least favorite part of the jo) Vlt of 32% ceramic metered at 25-27% where as hp 30% metered 31% I haven't checked dyed express with a meter as of yet. Good luck. 

1.0 is 1 mil dyed, 1.2 is 1.5 easier to work with imo. Classic black is express brand a good film that's easy to work with. Their cool people give em a call and ask! Thumbs are getting tired here....
