I have a couple of polished steel plates that are going to be used as
parts of a hinge system for a gate I'm installing. I want to keep the
shiny, polished steel appearance, but I don't want it to get rusty in
the outdoors. I was thinking of putting on a clear satin lacquer. But I
don't want the lacquer to show up as a plastic coating on the steel.
Anyone know a good product to use for this purpose?
Didn't even think of stainless. However I would paint the stainless
where it touches any non-stainless (unless the other metal is aluminium
of course) with an anti rust paint.
If you put stainless next to a non-stainless metal, corrosion seems to
be more aggressive, possibly a galvanic reaction. Just paint where the
stainless touches the other metal, and things will be fine.
If you have made your components already, there is no coating that will
last a long time. Having a high polish on the steel plates will allow
you to keep them rust free for a while at least.
In my limited experience, this is the stuff:
It isn't cheap, but it is excellent. Note that UPS will hit you for an
extra $20 since it is considered a hazardous shipment.
I just brush on and use locally bought lacquer thinner for cleanup; if
you buy thinner from them, you'll pay additional hazardous shipping. If
you are spraying it, you might want to consider their thinner though (I
know nothing about spraying).
Permalac includes ferrous corrosion inhibitors (don't ask me how they
work), which is how they get the scratch test results. This is where
they deliberately scribe through the coating and then put the metal in a
corrosive environment--still doesn't corrode.
I've used Permalac on an exterior steel blacksmithed sign mounted on a
brick wall. It had been up about 12 years last I saw, with no corrosion.
That said, this is in Loveland Colorado, which has a much more benign
climate for exterior iron than places like Maine, for example. I used
gloss, it is definitely glossy, but I wouldn't say plastic looking. They
also have matte now.
who has just ordered a gallon of gloss to apply to exterior iron where
he lives now, in Maine.
Thanks Steve for your highly relevant response. Other people were
talking about stainless steel, when I already said "I have a couple of
steel plates". I suppose I should have mentioned, I've done a lot of
work to these steel plates to make them into ornamental pieces -
Throwing them away and starting with stainless steel is not an option.
Besides, I doubt stainless steel would have the old world aesthetic
that this regular hold rolled steel has.
Thanks again, i'll try to get ahold of that stuff in Matte.

Yes Steve's response was -gold- but the others were simply telling
you "it pro'bly ain't gonna work unless you get something mighty
special" in a back-handed sort of way.
You're not too-good to be back-handed are you, Raffo? ;)
