Great product! Life-Caulk
I use Life-Caulk all over my boat and factories. I've reinstalled new windows, deck fittings, and on a 40 year old boat, I've used Lifecaulk on and around every exterior screw and stanchion to prevent seepage. I have even used it on the rubrail that has the seam where the top and bottom meet. Further, I used it on a steel ball tumbler, on a crack, to prevent leakage of powder. It lasts!
