I found some leaks on my boat, The first is at the tip of the bow under the aluminum edging. Can I bust broadly apply some gloop or do I need the take the edging off? What sort of gloop is recommended. The second leak is from under the splash guard. How do i get that thing off or can I just apply some gloop to the entire guard edges? How do you get the rivets off? Once off what do you replace them with? Also,,I have a small 1 inch ding in the guard edge. Will marine tex work for that? Also,,, Also....on the very bottom of the boat the white is rubbed off at the centerline. Is that anything to worry about?Thank you.Thank you.
