Well packaged and easy to use

### ⭐⭐⭐⭐ Great stuff.
*by C***H on 11 February 2026*

Good stuff, did the job. Worth knowing that if using in any kind of situation where it is squeezed under tension and left over time (I used it for mounting boat rubbing strakes) that it will continue to squeeze out in areas, particularly in hot weather.
