Alright, sounds like a plan.
I noticed you were also talking about tint regulations for your area, and you weren't sure of percentages. Oddly, your state's government website does not list laws and regulations online. This is kind of weird.
From what I gather from searching, any tint that is legal under Federal law as stated in FMVSS205 is legal in PA.
Title 75 of PA statutes 4524(e)(1) says that it's legal as long as it doesn't prevent someone from looking inside the vehicle from any window.

Stuff you might want to read.
Interestingly enough, if they sell Hyundai Tucsons in your state with factory tinted rear windows, then 35% should be legal all the way around, as my wife's Hyundai's stock tinting is darker than the 35% I just had applied to my Versa.
