Rust on Stainless
Good day listees and Happy Holidays!
I'm going around the boat and planning on fixing all the stainless bases on
stanchions and bimini top supports where there is rust. FSR and Whink seem
to get most of the rust off the fiberglass, but don't seem to help the
stainless. I am replacing all the stainless screws as I remount, which is
where I think most of the problem is with the rust. Should I also replace
the stainless fittings? That would be very expensive to replace them all,
support and stanchion bases. Put something on contact points between
stainless and fiberglass?
I also use Collinite's #850 Metal wax to get rust off the stainless railings
which works getting rust and spots off, but doesn't seem to protect the
stainless very long.
Is there something else that would be better to protect the railings longer?

If the rust is coming from the screws, be sure to replace them with 316...
you may have 302 in there now, and they are rusting. Remember, it's
stainLESS, not stainPROOF. For "ghost rust" that little brownish tarnish SS
gets, I have good luck with Nevr-Dull. It's a wadding with some chemical in
it that cleans the SS and at least seems to protect it a little. For heavy
stuff, and other metals, 3M's metal restorer and polish is great, as are
Simichrome polish and Flitz. As far as rebedding, I personally prefer
polysulfides like Boatlife, although other materials can be used, as well as
physical gaskets.

Hello Michael:
Underneath fittings and around the fasteners should not weep rust. If they are, the bedding, if present, has failed. All fittings need to be bedded to keep moisture out. The rust is coming from wetness- water, rain, condensation, dew, etc. Bedding in a tube does not work forever as many people assume it will. I assume it will only last for 5 years, max, but more importantly, the bedding in some places will last even less, especially if the fitting is not installed correctly when using this type of sealant. The trouble is that you cannot guess at which places the bedding will fail and when. This is why I favor the oil-based bedding compounds, such as boatyard bedding compound sold by both Interlux and petit, not just for wood, but also on fiberglass and metal components. I have been using it for years and have much better results with it than with the "tube" compounds. Once you use it, it is very possible to never go back to the tubes unless you have a specific
application that requires it. It is easier, not as messy, cleans up with paint thinner, can be given some rot resisting properties by adding copper napthinate (or a like compound), but best of all, it allows the fittings to come apart easy, is easy to clean off ,much more fun to apply and although I have not done an indepth evaluation, it is my impression it is cheaper. Give it a thought.

Don't forget Whink to remove stains on stainless.

Rudy, That sounds interesting. I'd like to find out a little more about
it. I'll check around FLL for one of the suppliers to see who carries it.
Anybody else on list have any experience with it?
