I thought I should start a new thread on this awesome rub rail of mine! 42' Sunliner rub rail from factory came with a 1-1/4'' thin walled ''Cap'' fastened directly over the molded in shoe box hull to deck joint. Which is barley that. Hull to deck joint just kind off meet together and do not over lap. The factory bedded the joint and rail with sealant, no rubber or plastic base what so ever. So the bump / shock resistance was minimal being directly mounted to the hull. From my observations, Ocean has had various incarnations of how to tackle the hull/joint rub rail section. Mine being the worst. Over the years from previous owners ( never me!), various dings and impacts , have loosened up sections of the rail and screws to let water get behind and into the deck joint and cause leaks and trouble ...etc. Causing the screws to come loose and let water get in and cause the rail to get loose. This is also compounded by others over tightening / over sizing screws to the point the hold nothing.... So I'm removing the entire rail, cleaning out the joint/base the best I can . I plan to fill in the screw holes with a combo of epoxy on the large ones, and 5200 on the small ones. I plan to start a new hole pattern with the new rub rail. So I just want to seal them up to keep water out, not to hold a screw. Then I plan you use 5200 applied with a ''bazooka'' caulk gun, LOL, into the joint , then smooth it over and press it in with a putty knife/finger making sure there are no open gaps. The new rub rail I'm getting is TACO V11-9798 1-5/8'' x 5/8'' flexible rub rail to which a 3/4'' hollow back stainless steel insert rests over the flexible rubber rail. This flexible base is the part that was missing in the first place. I am going to post a few photos of the project from my phone, I hope they work and are not to big. Please let me know if they are and I will remove them/stop.
