I had the same problem too last summer with a sheet of jessup. Within the first few minutes of skating the sides started to chip and peel away, just like the picture above. Not only that, but I saw that a ton of other dudes at the park who had jessup on their boards had their griptape peeling like that too. I called the shop and they told me that it was just a bad batch of jessup and they threw it all out. Had to regrip my board and everything, couldnt stand looking down at my board and seeing the grip all fucked up. After that I just stuck with mob and shop brand grip, didnt want to risk putting jessup on my board and having it fuck up again.
I actually just got a board a day or two ago and put jessup on it, first time skating it again since last summer when the whole bad batch mishap happened. Havent gotten a chance to skate the board yet. Hopefully it doesnt start peeling and chipping away on me again.
