Ummm...Yeah I have a healthy amount of tractor supply stores in my area. Black might work...

Ok I have an issue unfolding in the viv...I put silicone on the glass where I was to spray foam. Yesterday I noticed that one area the foam was separating from the silicone. This just so happened to be an area where I had removed some foam that was a, "hey I have more foam in this can let's use it...um, here!" decision, that turned out to be a bad idea in hind sight. But today I noticed it was separating from the other side. Both happen to be the side glass not the back. What should I do to fix this? Smear wood glue into the cracks?
