"Looking for a problem" <-what's that? Anything more specific as to what that could include? Strikes me as an odd thing to say. Your window is glass, so your ok there. You have a defroster, so to most cars with glass rear windows. I'm not sure what the concern is all about.

Tinting the side windows gives a decent amount of protection from my opinion, but without having the rear tinted, it looks odd. You're in FL, get the back window done!

There is the argument that having the top down with tinted windows is a bit of a paradox, but then again -it's your call.

I've thought of tinting my windscreen but was informed by my tinter that it doesn't stick to plastic all that well.
