Review on GYEON Quartz Q² Tire - Ultimate Sio2 Ceramic Coating for Tires - Long-lasting Durability - Car Detailing - UV Protection - Luxury Tire Coating - Enhance with Tire & Wheel Cleaner by Gary Shakeone

Washed out after the first rain. I followed the directions to the letter and even tried using a heat gun on my tires to improve the finish, but the material got washed away by the rain just as one of my cars was parked in the driveway. Although it went on. light and left a nice glossy sheen that almost disappeared when it rained. And yes, I cleaned all the tires fairly thoroughly and used a Master Blaster air dryer to ensure the tires were completely dry. I can't believe all of these wonderful reviews. Considering the amount of effort I put into using a heat gun to prolong the life of this product, this product is incredibly disappointing.
