I have a liner that is rubber, it's a fairly thick one and isn't that old. We had it folded and stored for the past 3 years. I laid it out yesterday and discovered it has about 5-6 holes in it. They are about 1 1/2 inches long and 1/4 inch wide. Not just cuts, but looks like holes. Someone told me to use a tire patch, but I went to the store and the ones I found are self adhesive. I just didn't think they felt that sticky to me and I wondered if the adhesive is safe for fish. I just have no idea how to fix these. I was told to patch both sides of the holes. I do still have some liner scraps leftover, but I don't know what kind of glue to use. Please someone help me save my $400 liner!
