Purchased this product about a year ago for a hole in a vinyl pool liner. I had low expectations going in so I was happily surprised when it stuck instantly and held tight. Bought it again recently and couldn't get it to stick at all except to the part that was completely dry. Very disappointed. Did they change the formula? Oh well, if this had been my first experience I wouldn't have been surprised. Thought I had a good, convenient way to fix small holes. Now I don't. I won't waste money on it again.
Pros and Cons:
Bottom Line: No, I would not recommend this to a friend
