Jim you are correct , dis-similar metal corrosion would indeed take place ,
and aluminum corrodes very quickly in those instances , especially when it's
already fighting salt water corrosion .

Perhaps I misunderstand you, Steve, but my experience suggests that
bronze is not good for fastening aluminum. I stick to stainless, or
possibly aluminum rivets, for mounting aluminum fittings. It looks
better, too.

I suggest powdercoat is the best way, but powdercoat and paint do not
like
sharp edges. All edges must be radiused. Any break in the surface
treatment
will allow water to corrode the aluminum and the corrosion will lift the
coating. Pay close attention to holes for fasteners. They must be bedded
with a sealant. If you cannot do this, use stainless or bronze.

There are many aluminum components on my fiberglass sailboat such as
windvane components, electrical housings, mounting brackets, etc.;
some
of which are of substantial thickness and size.

I'd like to improve their appearance and durability in a marine
environment.

What works and looks good too ?

Thank you.
