Query: Horrible directions & product

Very thin material and it completely curls up and melts when you apply the glue as directed. Patch material then shrinks up when glue dries so patch looks awful. I strongly suspect it won't hold water well and won't last even if it does.Take a $1 inflatable toy and cut it into strips. Add a $1 can of PVC glue and you have this entire kit.
