Review on XFasten RV Repair Tape, White, 4-Inches By 50-Foot, Weatherproof RV Rubber Roof Patch Tape For RV Repair, Window, Vent, Boat Sealing, And Camper Roof Leaks by Kevin Fuentes

The role has places where you can see in the picture that has no material you do have to massage it to make it stick and I guess they figure you'll move it back and forth and fill their mistakes the cellophane on the back is hard to get off tears and all kinds of directions and leaves little pieces on the sealant which I found out after I put a piece on and had to put a ugly patch over it which is the only way you're going to seal that up it turned into a pretty good mess good luck with this product
