FAQ

▍Q: Why choose HQ-7590 with 76% VLT — a nearly clear film?

A: HQ-7590 is designed for drivers who want maximum heat and UV protection with virtually no visible darkening. At 76% VLT, it is nearly optically clear while delivering 94% infrared rejection and strong UV blocking. It is ideal for: front side windows in strict-VLT jurisdictions (70%+); windshields (where legal); luxury vehicles where the owner wants to preserve a factory-clear appearance; and anyone who prioritizes cabin comfort without the "tinted" aesthetic. It proves effective solar protection does not require dark glass.

▍Q: How can a nearly clear film block 94% of infrared heat?

A: HQ-7590 achieves this through selective spectral filtering — its nano ceramic particles target specific infrared wavelengths (780nm-2500nm) while allowing visible light (380nm-780nm) to pass through. This is fundamentally different from dyed films, which reduce heat by darkening the glass indiscriminately. HQ-7590's ceramic technology separates heat blocking from light transmission — heat is blocked, clarity is preserved. It applies the same principle used in high-end architectural window films, adapted for automotive glass.

▍Q: What does the 10-year warranty cover, and why does HQ-7590 carry the longest HQ warranty?

A: The 10-year manufacturer warranty covers material defects, delamination, cracking, peeling, and excessive fading. The extended coverage reflects HQ-7590's premium nano ceramic construction — ceramic films are inherently more stable than dyed or hybrid films. Warranty claims are processed through the authorized dealer using the product's batch code for traceability. For installers, the 10-year warranty is a powerful sales tool — it positions HQ-7590 as a decade-long investment in vehicle comfort, not a disposable accessory.

▍Q: Can HQ-7590 be applied to the windshield, and is this legal?

A: Technically yes — at 76% VLT, it exceeds the 70% minimum for windshields in most permissive jurisdictions. However, windshield tint regulations vary widely: some regions permit clear heat-rejection film on the entire windshield, others restrict it to the AS-1 line, and some prohibit any film. Always verify local laws before windshield application. When legally permitted, a professionally installed HQ-7590 windshield application dramatically reduces cabin heat — the windshield is the largest glass surface and primary solar entry point.
