A while back I posted the rebuild of our companionway hatch cover. Moisture damage. Now I need to reinstall and caulk the seams. After reviewing so much online information, I remain confused as to the best choice to caulk these seams. Not 5200, other 3M sealants yellow, some chalk like Lifecalk. What have you use with success? Tools easily, stays white and clean, isn’t permanent, etc.
