Review on 🏢 Cofair UBE425 Quick Roof Extreme White 4-inch x 25-foot by Kevin Gray

When laid on a perfectly clean, dry and relatively flat surface, it adheres quite well. The vertical angle on the wheel arch also worked surprisingly well. However, the horizontal angle on the roof does not look so good. Keep in mind it wasn't necessarily the cleanest surface. I ended up using OSI around the perimeter of the pieces, which didn't seem to stick either. It worked like a charm and there is no chance of a leak. It's really well made and just for a quick and reliable fix. I suggest putting it in the sun for a while before installing to heat it up and activate the glue. I leave a spare of these in the RV in case we are on a trip and we have an emergency leak. It was also deployed out of the blue on an 8-person inflatable island. It easily seals standard pipe material. Held air and all water. I sincerely think it worked better than on a camper van in most cases. Probably simply because the pipe was flat and the camper was clearly full of dents and dents.
