Hon, I have found there is a HUGE difference between the regular tape and the waterproof tape...the store brand and brand name tape. I have found that if you get the brand name waterproof tape, that holds the absolute best. Rub the area with alcohol first, ESPECIALLY around the edges of where the patch will be, apply the patch, then put the tape on around the edge of the patch, and one ACROSS it. I've found that works REALLY well. If you don't get the edges with alcohol really really good, and they start to come up, the entire patch will come up. The edges are most important.

Perhaps try that next time ???
