I patched a small hole in my Wilderness Pungo kayak with this kit. After watching a video on uTube I thought it would be better to use stainless steel mesh for reinforcement as the hole was actually at the end of the kayak which sometimes pulls. I was a little nervous that the kayak would "melt" while gluing the net, but after overcoming the initial fear of wrecking my boat it was actually fun. I put several layers of polyethylene on the mesh and I think it's better than new. I still need to sand down some of the roughness but I'm very happy with the result. Now my kayak has a reinforced stern and is waterproof again. At first I thought $129 was a pretty steep price, but it's a lot cheaper than buying a replacement kayak for $900! I am completely happy. Good product.
