### ⭐⭐⭐⭐⭐ Held back water amazingly!
*by M***E on April 20, 2025*

A definite need if you live in a flood zone! I'm still tryto figure out why FEMA, counties, and cities still tell people about sandbags. They don't work where FlexTape is magnificent! I live in a flood zone in Florida near Tampa Bay. We have 39' of new French doors along the back (waterside) where we added a 1000 s f addition. Taping saved our home during Helene and Milton! For Helene, neighbors thought I was overreacting, but, we never had to leave our house whereas most neighbors are living elsewhere still...7 months later! I told our county and FEMA folks to stop telling people to sandbag! FlexTape will save your home! I won't lie...it's a tough job to tape all doors, etc...up a few feet, but that's what makes adhesion work so well. I'm sure 67 y o with shoulder and numerous hand/elbow issues...but i did it. FlexTape...advertise on TV, internet, etc ..through hurricane season! I've been advertising for you (and another cheaper tape for other areas) to neighbors on the Next Door app. One lady asked that I remind everyone during storm season.
