Key Features

• Ultimate Waterproofing: Instantly seals leaks and prevents water intrusion on roofs, seams, and joints. Ideal for RVs, campers, and mobile homes, as well as tank repairs and odd-shaped areas.
• UV Stable & Durable: The black, specialized backing remains UV stable after years of sun exposure—proven to last over 16 years in full sunlight without cracking or fading.
