GYEON Leather Coat is a ceramic-based leather protector that creates an invisible barrier on your car's interior upholstery. It delivers long-lasting hydrophobic performance to help repel dirt, sweat, and stains—while preserving the leather’s original look and feel. Designed for use on all types of automotive leather and synthetic upholstery, it defends against UV rays, fading, and heat damage. Though it cannot fully prevent dye-transfer in all scenarios, it significantly improves your ability to wipe it away cleanly, especially from high-contact areas like bolsters or seat edges. Application is fast—simply wipe onto a clean surface using a microfiber cloth or applicator and allow it to cure. With protection that lasts up to 3 months per use, it reduces the need for frequent reapplication. GYEON Leather Coat is ideal for detailers and DIYers who want to boost interior protection without affecting color tone, breathability, or texture. Use as a final step after cleaning to lock in cleanliness and enhance resistance.
