    I just tried it for the first time. So it will take some time for me to know if it does what I used it for. But so far it seems to be sealing the ground level windows from the high water from the last rains. You need to have a category that says - You have not had it long enough to know how well it is working.

    OSI Quad performs great. I use it on all windows and doors, basement crevices, etc. It holds, doesn't shrink, easy to smooth so it looks great, and its paintable. Leftover cartridges if stored well will have a pretty long shelf life until you need it again.
