Review on EternaBond TAN Mobile Home RV Rubber Roof Repair Tape Sealant - 4 Inch x 10 Feet, 10 FT by Nick Brunner

I bought this tape to seal a newly installed exhaust fan. Unfortunately, the roll of tape I received is unusable. As another reviewer noted, there are creases in the tape where the glue is completely missing. These folds occur along the entire length of the tape. They run along the tape in such a way that I believe water enters the entire perimeter of the ventilation fans. I didn't unwind the band to test it when it was delivered, so I wasn't aware of the problem until the return window closed.
