Review on 🛠️ Patch & Shield Power Tape Black: All Weather Stretchy Sealing Tape - Waterproof, Ideal for Roofing, Pipes, Holes, and Cracks! Butyl Tape 4 inch x 5 feet by Jim Young

I set out to use this to repair a couple of 6-10 inch cuts in a durable vinyl sheet that I use in a creek style pool in my backyard. I drained, dried and cleaned the area to be patched. I apply tape over cuts, smooth to remove any bubbles or waves and let dry for 48 hours before refilling the water feature. Unfortunately, after a couple of hours, it turned out that the repair didn't hold up and water was seeping through the cuts. It was really tacky and when I put it on I had positive expectations that it would work. Very disappointed that this did not happen. So I replaced the entire liner with 45 mil rubber roofing. I contacted Gaffer to get my money back and they responded within minutes. Such great service and refund for their product!
