The Liquid Rubber RV Roof Coating kit is a comprehensive solution for anyone looking to seal and protect their RV roof. This kit includes a 5-gallon sealer, 1-gallon EPDM primer, a smart cleaner, seam tape, and lap sealant, making it an all-in-one package for roof maintenance. One of the standout features is its flexibility, with the final membrane boasting over 1000% elongation, which helps prevent adhesion failure. This product also offers excellent UV resistance, helping to protect your roof from sun damage, and its solar reflective properties can keep your RV cooler in hot weather.

Additionally, it's environmentally friendly, being water-based and free from solvents and VOCs, ensuring safety for both humans and pets. Application is straightforward, similar to painting, and it can be done with a brush, roller, or high-quality paint sprayer. The 5-gallon pail is sufficient for RVs up to 30 feet, requiring 2-3 heavy coats for optimal coverage. However, it's important to note that full kit returns are the only accepted return method, which could be inconvenient if you don't need all components or if there's an issue with part of the kit.

The product weighs 40 pounds, which might be a bit heavy for some users to handle alone. This kit is ideal for RV owners looking for an effective, long-lasting roof sealant that is easy to apply and environmentally friendly.

The Liquid Rubber RV Roof Coating is a versatile and effective solution for sealing camper and trailer roofs. As a solar reflective sealant, it promises excellent UV resistance, ensuring that the product remains stable and effective even under prolonged sun exposure. Its high flexibility with over 1000% elongation helps prevent adhesion failure, making it a durable choice for various weather conditions.

Waterproofing is a key strength, preventing leaks and protecting the roof's integrity over time. The ease of application is another plus; it can be applied using a brush, roller, or paint sprayer, similar to painting, which makes it accessible for DIY enthusiasts. The environmentally friendly, water-based formula with no solvents or VOCs is safe for both indoor and outdoor use, making it a responsible choice for those conscious about environmental impact.

However, at 44 pounds, the 5-gallon container is quite heavy and may require extra effort to handle. Additionally, achieving the recommended thickness might require multiple heavy coats, possibly increasing the application time. Despite these minor drawbacks, it is a reliable and favored option for RV roof maintenance.

The EternaBond RoofSeal Black tape is a strong choice for camper roof sealing thanks to its one-step application and durable, waterproof design. It uses a thick 35-mil MicroSealant layer combined with an aluminum backing, creating an airtight and moisture-resistant barrier that works on many surfaces common to campers, like metal and fiberglass. Its flexibility in cold temperatures (down to -57°C or -70°F) helps prevent cracking in various climates, while the UV-stable backing protects against sun damage—important for roofs exposed to long sunlight hours.

Applying the tape is straightforward because it doesn’t require extra sealants or messy tools, making it convenient for quick repairs. The tape also resists abrasion and corrosion, which adds to its lifespan on the roof. However, its upper temperature limit of around 150°F means it might not be ideal for extremely hot environments. Also, while the tape works well for repairs, it might not replace full roof replacement in severe damage cases.

This product is well-suited for camper owners or RV users looking for a reliable, easy-to-use patch for leaks and cracks that will stand up to weather and sunlight over time.
