    sticky stuff
  

*by R***R on Reviewed in the United States on October 11, 2013*

This caulking does its job but it is hard to put on. We all ended up with the sticky black stuff on our hands.

    Good adhesion stays flexible with an unbeatable price
  

*by W***. on Reviewed in the United States on July 6, 2015*

Good adhesion stays flexible with an unbeatable price, The only down side is it is very thick and hard to pump out of the tube.Bill
