Re: Caulking bottom of new rope clutches
There are numerus options other than SS. SS looks nice, but so can other options when painted, making them less visually obvious than SS.
Aluminum. Broadly available, light, easy to work. Won't corrode unless you are leaking seawater, which you shouldn't be.
FRP. Very effective when bonded to the hull. No corrrosion.
Dolfinite? Polyurethane? Bulyl? It depends on the application. Polyurethanes are quite adhesive and removale can be trouble. Butyl allows easy removle, is VERY waterproof, but relys on a good mechanical mounting. Donfinite is middle ground. I use all of them, but I think I would go for butyl in this case because...
* a good mechanical mount will be provided.
* flexing is posible.
* removal is possible.
I'll generally go will polyurethane for screw-mounted hardware, where a little extra bond helps.
