Does your glass become waterlogged and crackled every time it rains? Ordinary waterproofing agents fail within days, but IOTA silicone creates a lotus leaf effect—water droplets roll off like pearls, leaving no trace! With the recent humid weather in southern China, foggy car windows are extremely dangerous. Just spray and wipe with this, and your glass will be sparkling clean, completely waterproof. Real-world testing shows that the water droplet-rolling effect is more durable than traditional products, making it safe and worry-free!
