Hey Rob -<P>I have 50% on the front side windows, and 20% everywhere else. If I had to do it again (and I did on my other car) I'd do exactly the same thing!<P>I like 3M, Llumar, Johnson...in that order. I'm sure there are other great films out there, but these are the ones I have experience with. They all have lifetime warranties (if your Llumar was degraded, it should have been replaced for free by the mfg) Have an autorized dealer of the film you choose do the install, and you should be covered. I've found good tinters by asking local auto dealerships who they use. Then I call and talk to them. If they brush me off, or don't have time for me, that's the last they hear from me. When one sounds good, ask to drop by and see a car he's done.<P>Look to spend about $250-$300 for all the windows. Most I've heard is $350. Remember the 80% net for the front windows is the max legal here in CA. 80% is all but clear (factory tint is in the 85-90% range). You can do ANYTHING on the windows behind the front seats.<P>I have had no negative effects on radio reception. I know others have reported it, but it simply does not effect mine. The antenna, of course, ends up to the outside of the tint. I have noticed cell reception to be a bit reduced inside the car with the windows all up. And I know it's the tint, because rolling the windows down improves the reception. Hasn't been a show-stopper though.<P>I recommend the semi-metallic films. They take longer to dry, but in the grand scheme of things, a couple of weeks is nothing compared to the benefits. To me, the looks alone would be worth the price of tint, but I did it for UV and heat protection. I can't say enough good things about tint.<P>- Darell
