Leave a Tip

If you found something on this site helpful, learned a technique from a video, or just want to support a small Texas shop cutting ceramic tint for the DIY community — every tip goes straight back into faster shipping, more vehicle patterns, and better content. No pressure, ever. Completely optional.

Tips are non-refundable. Shipping still applies if tip is added to a cart with physical items — or add the tip on its own for zero shipping.

Union Ceramic IR film: Performance varies by shade, with up to 87.6% infrared rejection, 99.99% UV rejection, and 1.5 mil, 2-ply non-metallic construction.

Shade selection notice: Window-tint laws vary by state and glass location. The buyer is responsible for selecting a shade permitted for the intended application. For street-driven vehicles, verify full-windshield and windshield-strip limits before ordering.

Free 30-day returns and exchanges

Every return and exchange is free — including the return shipping. Opened, partially installed, or wasted film is all covered within 30 days of delivery for a full refund of the product price or a replacement kit, with no restocking fees. Start at hmu4tint.com/pages/returns: create your free account, submit the return form, and we email you a prepaid return label — you pay nothing to ship it back. The one condition: send back all the film pieces (used or unused) together with the original shipping tube, neatly rolled with the original packing, ends capped and taped — returns that are forcefully stuffed into the tube or intentionally damaged can't be accepted. Wrong fit? Email hmu4tint@hmu4tint.com within 14 days of delivery with your order number and photos for a free replacement or full refund — we cover all shipping. See our refund policy.
