Hi Bob, I've been thinking about this too. I believe it would be very easy to tint as the windstop can be removed and you could bring it somewhere. In my other cars I've had this type of tint in for years and it look pro, no bubbles and the tint hasn't discoloured - it looks factory - even over the defroster lines - but it is scratchable with a key or sharp object, so there is some care involved.
I had to go to a special tinter that uses high quality tint - not the stuff you buy in the stores. It would probably cost about a hundred or so, but it would look factory. Contact your dealer or other dealers in your area to find out who does the best work and has the best product, check their work, then do it.
My only concern is that it is darker at night. Since I don't drive at night a lot, it probably wouldn't matter much though. In the day, it would probably look pretty hot ..... but then you'd want to get your windows done then too ....... which is illegal here. I've got it on the rear and don't really notice much of a problem, it actually cuts down on headlight glare ...... but it is definitely darker.
You can get various visibility and UV tints (ie. 5, 10, 20, 40% block, etc.) and some use lighter for the sides and darker everywhere else. May get this done, but it's not that important to me yet.
Hope this helps you and others, cheers
