Has anyone had any luck repairing a roho cushion? I bought a new low profile roho about a year ago to sit on while in a car seat. Last weekend it lost all of the air, found a hole/split in the seam on the side of the cushion (where the top and bottom layers come together). I filled the split with something called "gorilla glue". It's drying right now. Don't know how trustworthy it's going to be, would appreciate any advice if anybody has been able to successfully repair a split like this.
