Ceramic rejects noticeably more heat and infrared at the same shade, so the cabin stays cooler without going darker. Confirm your state's tint laws before choosing a shade.

- Can I return a precut kit?
- Unopened kits can be returned within 30 days. Opened or installed kits are final sale, except pieces damaged in shipping or patterns that don't match your vehicle — those we replace free. Unopened kits must be in original condition; the 30-day return window starts on delivery and eligible returns receive a full refund. Cut for your exact year, make, model and trim. If a piece doesn't fit your vehicle, we recut it free. If we can't make it right, you get your money back. Contact support@precutly.com for help. Support hours are Monday–Friday, 9 AM–5 PM Eastern Time.
- Why do you need my VIN?
- The VIN confirms the exact model, trim and body style so the correct pattern is plotted. It is optional at checkout; we will request it by email after your order if we need it to confirm fitment.
