      • THE Best for my needs

      Simply put ... the best stuff for my uses. After wrapping all the exposed pipes on my well & plumbing system with a protective foam, I overwrapped ALL the pipes with this tape. Now, nearly 4 years later, these exposed pipes with this tape look just as good as the day I installed it. This stuff sticks VERY well. Being that it feels like a heavy aluminum foil, it holds up well to the elements & abuse. Just bought another roll today to wrap my much smaller 1” exterior, exposed PVC pipes after installing a split foam protection. Has other great uses with heating, vacuum & A/C systems & I am confident it would perform much the same. Little pricey, but it costs a LOT less to do the job right the first time when compared to doing it again in a few short years.
