This is one amazing product. I have used it to seal my basement wall, and used it everywhere on my travel trailer as I was restoring it.
I purchased a used 2000 model Coachman 25-foot travel trailer. The wheel well wasn't sealed which allowed water to enter the interior and rot out the floor, which was the reason it was sold as a "fixer-upper". I sealed the wheel well with Flex Seal tape and coated the remaining well with the spray-on Flex Seal. The floors were replaced and the subflooring coated with Flex Seal. Then the floor was covered with laminate flooring. The roof needed repair and I used Flex Seal tape to seal the edges and all the flanges of any vents. Then coated the roof liberally with Flex Seal liquid white. Lastly, the trailer's awning appeared to need replacing. I found only the first 8 inches of the awning had sun rot. So I coated the entire length with 8-inch Flex Seal tape. Then sealed all edges with white liquid Flex Seal.
My wife and I used the travel trailer all summer. Not one issue with any leaks. I strongly recommend Flex Seal to anyone who has a need to eliminate water from entering their home, or camper. Excellent product. You must follow the manufacturer's recommendations and to be sure to clean surfaces before applying.
Bottom Line: Yes, I would recommend this to a friend
