Frequently Asked Questions

Q: Will this waterproof sealant work on painted car roofs without leaving a visible residue?

Q: How long does the waterproof sealant last after application on a sunroof or car roof seam?

A: When applied correctly to a clean, dry surface, the cured sealant creates a durable, flexible waterproof coating designed to withstand temperature changes, vibration, and weather exposure over time. For best results, reapply as part of your regular vehicle maintenance routine.

Q: Can this sealant be used on surfaces other than cars?

A: Absolutely. While it's specifically designed for automotive use — car roofs, sunroofs, door seals, and window frames — it can also be used on RVs, vans, and similar vehicles with plastic, rubber, or metal exterior seams that need waterproof protection.
