[Public-List] Sail track rivets on mast - SS Machine screws

[Nicki Crutchfield]

Hello all,
My first post after much reading here. 
Monel is the preferred option here in the UK. It is apparently inert when mixed with aluminium and, though more expensive than aluminium ones, I wouldn't use stainless. Depends if you are in a salt water environment or not. The black goop (whatever it's called) is also the way to.
There, I've made my maiden post.:)
Kind regards,
Nicki.
