I bought this to seal a flange around the shower neck that come out of the wall. It worked great, set very quickly, and has now held for some time without any signs of loosening. The smell dissipated quickly and I appreciate that they give you a tapered tip to use. The tip can be secured onto the tube when you’re storing it. Just clean the tip out (I used a toothpick), place the ring around the neck of the tube, and put the cap in place to keep it from drying out. Super handy!
