Window Tint
Tint that holds up to Ontario's airport-corridor traffic and sun.
Ontario cars sit in a lot of stop-and-go around the airport and the Mills mall corridor, which means long idle time baking in direct sun. We'll break down California's legal limit for front windows and which film grades actually lower cabin temperature instead of just looking dark.

What you get
- California's front-window rules, in plain English, before you get a fix-it ticket.
- Dyed versus carbon versus ceramic film, and where the extra money is worth it.
- What heat rejection numbers mean, and which ones shops quote to look better.
- Warranty terms: lifetime against what, and honored by whom.
Watch out for
- Fleet and rental vehicles common in Ontario often carry aftermarket tint installed to a lower standard — check the actual film spec before assuming it's compliant.
- Vehicles parked at Ontario International long-term lots sit in full sun for days; ask about UV and fade warranty coverage specifically.
- A shade that reads legal on a meter in the shop can test differently once the film ages and darkens further.
- HOA and lease-return vehicles sometimes require tint removal — confirm the film is safely removable before installation.
