Window tint is a thin film applied to the inside of your glass. Quality ceramic film blocks the infrared heat that bakes your seats on a July afternoon, cuts the glare that makes a bright commute miserable, and filters the UV that fades dashboards and seats over time.
It is not just about looks and we will not pretend otherwise. Cheap dyed film turns purple and bubbles within a few seasons, and shade that is darker than Minnesota allows turns into a fix-it ticket. We would rather talk you into a legal ceramic that performs than sell you a shade you will have to strip off.
If you drive kids, park outside, or just want the cabin to stop feeling like a greenhouse, tint is usually the most noticeable comfort upgrade you can make for the money.
