A repair is only as good as the materials and workmanship . A patch is considered better than a plug, but leaves the hole open , and moisture can get in between the plies and cause separations and problems over time, also you get get problems with separation with plugs . Popping out is just a bad job , and has been known to happen . A patch plug will seal the liner from the inside , and fill the hole to keep moisture out .
