The 35% is only available in ceramic, which is why it's more expensive. The Tint-Pros site shows an extra $50 for a full tint job with ceramic, but they might discount that a bit for mnmazda.
For anyone contemplating getting tint done, but not sure...Tint Pros is awesome when it comes to clean quality work. I've had tint on my car for 3yrs now with zero issues. We also had my wife's front windows done by them 2yrs ago with no issues, and we had them do my father-in-law's car last Summer and he's been completely happy with the quality of the work. Highly, HIGHLY recommend Tint Pros.
