Long-lasting silicone formulation creates a deep dark black shine. Use it on any hard and soft exterior surface. For exterior rims, plastic and vinyl, molds, wheel wells, splash guards, and other rubber and plastic surfaces. It relies on solvents instead of water, making it highly water-resistant - it withstands harsh weather and frequent washing well. The high-viscosity formulation means less likelihood of tire runoff. Easy to apply, wipe, and clean. Keeps the appearance of tires black for weeks, not days. No running, no streaks - keeps your car paint clean!
