### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Excellent repair for leaky RV window
  

*by P***L on Reviewed in the United States on November 13, 2023*

Chose this to repair failed caulk around a RV window.  Easy to apply, sticks well, (NOT repositionable), and seals very well without edges lifting up over time.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    This stuff is the water-sealing "bomb".
  

*by C***R on Reviewed in the United States on August 11, 2023*

I used this tape in the shower in my barn loft apartment.  That apartment is DIY-city.  This tape provides a serious seal.  Imagine duct tape except the gummy, adhesive side has 10 times the gummy adhesive on it.  If you press it on real good, it even oozes out from the sides a little.  This is simple technology, but it works well.

### ⭐⭐⭐⭐ 4.0 out of 5 stars

*by C***L on Reviewed in the United States on August 14, 2023*

Use this to tape greenhouse plastic windows.  Some have lost adhestion, but others are ok.  Would recommend if not in outside elements to use.
