This sealant promises a durable, flexible, and weather-resistant seal, crucial for maintaining the integrity of RVs and preventing leaks.

Key Features:

  • Bright White Color: Blends seamlessly with many RV exteriors and interiors.

I bought three of these for the kitchen, laundry room, and bathroom. What I like most is that it doesn't just do leaks but also monitors humidity which is great for preventing mold in the basement. The app is pretty intuitive but I wish the battery life was slightly longer, though it’s not a dealbreaker given how fast it alerts your phone.

Nissan wanted a fortune for the OEM fluid but this Idemitsu stuff is the exact same thing for way less. My 2011 Rogue feels much smoother now and the whine is gone. Highly recommend if u wanna save some cash.
