5200 Underwater

mogul11 · #1 (**permalink**) 03-27-2003

Has anyone had experience with 5200 undewater. I want to attach something underwater and do not want to screw into the hull. My thought is to 5200 the ring to the hull and then screw in the screen for removal. The bottom is sanded down to F/G so I can interprotect the hull and then repaint. I would not attach to bare F/G and prefer not attaching to interprotect. My thought is to attach to the boat after bottom paint either VC17 or Dolphinite "GoFAst". Any thoughts on how 5200 would work? Thanks

There is no way you will get anytrhing to stick to VC17. Bottom paint is designed to preventy things sticking to it. If you want to use 5200 the bare fiberglass is the best surface to use. I wouldn''t worry about osmosis under the glued part.

What I am thinking is: Grocco makes a Bronze grate that can cover a thru hull. It comes in two parts an attachment ring and then a grate that can be screwed on to the ring. This way it can be removed for cleaning. I guess I could 5200 the ring to the bare F/G then interprotect around it and inside the ring. Then apply bottom paint inside and outside of the ring before installing grate. Lot of work but probably the best way to do it.

Why not use epoxy to hold the ring? It would work better than 5200. plus you could fair in around the edges for less resistance. And bottom paint will stick to it unlike 5200.
