In Florida I would expect it especially if you don't have dark tinted windows. The heat inside the car just bakes that adhesive off.

If I lived in Florida I would be probably at least 15% tinted or even 5% limo tinted to try and keep the heat down. A huge aspect that people miss is the heat coming in from the open sunroof too when the shade is open but the glass is closed, I had my tinted as well when I did my windows as you'd be surprised how much heat comes in from that even though the windows are done.
