Review: Good "putty" tape. - Solid, great for small repairs. I keep a roll in my rig, for " In Case" moments. Good tape, easy to work with. Buy a kids size pair of scissors, and put them in the box it comes in. Super convenient that way.
Review: It does the job just fine - Quality butyl putty tape is just perfect for use when installing old school windows on my vintage camper. Adhesion is fine and it's easy to apply.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Good "putty" tape.
*by P***N on December 14, 2025*

Solid, great for small repairs. I keep a roll in my rig, for " In Case" moments. Good tape, easy to work with. Buy a kids size pair of scissors, and put them in the box it comes in. Super convenient that way.

### ⭐⭐⭐⭐⭐ It does the job just fine
*by R***S on September 26, 2025*

Quality butyl putty tape is just perfect for use when installing old school windows on my vintage camper. Adhesion is fine and it's easy to apply.

### ⭐⭐⭐⭐⭐ An easy to use, two-sided sealant tape that provides not only a seal but also a cushion.
*by G***G on August 17, 2025*

I needed a good sealant that would not only create a closure around a mounting flange on a replacement water heater on our travel trailer but also fill in in areas that were uneven due to the corrugations of the siding on the outside of the trailer, itself. This tape provided all of those functions and was easy to apply, and clean up an excess that protruded after tightening the unit in place. There is a LOT on the supplied reel so there will be lots to do a fairly good sized job and the relative cost is in line with other types of this material I have used.
