Not sure what section this should be in: any way about two years ago I patched a whole on my liner and now it is starting to leak again. want to put a new patch on but want to remove the old patch first. Can you you remove a patch without tearing the liner?f so, how?Also when I put the new patch on how can I hold it in place (keep pressure on it) until it dries. It is right along the side where it starts to curve in the corner. Any help or suggestions are welcome.
