Wanted to follow up with the repair of my waders using the Flex Tape. Unfortunately, it was a failure. First, I tried patching them from the inside. It did not take long before they started to leak. The second time I patched them from the outside and again they started to leak. The only difference the second time was that the patch did not come completely off. The waders I was repairing were Breathable waders. The results might be different on the Neoprene of PVC waders.
