I have a tripple wall chimney of stainless steel that I would like to
color black.

Can I paint stainless steel with high temp Rustoleum, or should I wrap
it with galvanized or aluinium and paint that?

Thanks in advance.

you could try a sample area and wait for results.

and call the paint manufacturer and ask

Painting stainless steel is a bitch. Not sure why. The general
consensus is to etch the stainless with either chemicals (acid) or
sanding to give the surface some tooth so the paint will have a
fighting chance.

I don't know how hot the outside wall of a triple wall chimney gets,
but you may be able to get by with another paint, but Bob was right
that you'll have to do a test.

I wouldn't wrap the stainless with a different metal as you might
create a problem with galvanic action eating the wrapping metal.

Just use an etch primer that will allow you paint on SS or even glass.

I don't think so, Dwight, at least with materials that are available to the
average Joe Consumer. Did you ever wonder why the DeLorean cars were sold
unpainted? Stainless steels in the 300 series have the ability to form an oxide
on the surface of the metal that prevents, or at least retards, corrosion. This
oxide forms almost immediately whenever the steel is sanded, scratched, rubbed,
etc. making it very difficult to apply anyhting else to the surface and have it
"stick". Soldering is possible, although a real bitch, and I'd forego painting
because I'm sure it would only last until the next rain.
Enjoy your shiny chimney.

Try "gun blue" on a sample area and see if it works on SS.

I wonder if you couldn't get hold of a sandblaster to etch the surface
with. You might take it to a sand blasting company since it's Summer
and get it roughened up so paint will stick. I've never tried to paint
stainless steel so I would have to defer to an expert in painting
metals. I know how to paint galvanized steel by using an etching primer
but I don't know if there is a similar product for stainless steel.

Here's a link to a website that specializes in finishes, and the
experts there says stainless just has to be cleaned. Neither this nor
other sites I checked mentioned anything about using phosphoric acid
or oxalic acid, as is done for aluminum or regular steel:

Anything can be painted, it's just a question of how long it will
last, and a paint finish on stainless probably won't last long. The
OP didn't say where this chimney is located, whether he wants to paint
an interior or exterior section, and what the access is like. All
contributing factors to the approach.

Like one poster in that forum link said, painting stainless is an
uphill battle.

That's an opinion that a lot of people take issue with, Jim.
Stainless is passivated and that interferes with the paint bond.
Etching is required to improve the bond, but it's still not a sure
thing. Paint simply does not adhere to stainless as well as plain
steel.

Painting Deloreans is not as easy as you think. This from the wiki
entry on the Delorean:
"Furthermore, it is exceedingly difficult to paint stainless steel due
to difficulties with paint adhesion. DeLorean envisioned that damaged
panels would simply be replaced rather than repaired;"

When you say that Delorean owners had their cars painted because
maintaining the stainless was a PITA, that's a bit off the mark. It
was the little fender benders and dings in the door that prompted
people to paint their Deloreans. It's a lot harder to straighten out
stainless (notorious for work-hardening) than to slap on some Bondo
and paint. Most owners didn't have a real choice when push came to
shove - it was a cost effectiveness decision.

Here's an article where they opted to wrap vinyl instead of painting.
http://wheels.blogs.nytimes.com/2009/12/23/a-delorean-by-any-other-color/

I think the OP is barking up the wrong tree, but if he's adamant on
it, he should look into epoxy primers and a baked on finish. That
will be expensive and there's a potential for the elevated chimney
temperature doing funky things to the paint and off-gassing or
creating an odor.

I always thought the whole point to the stainless steel DeLorean was
a unique marketing angle, of dubious merit.

Gun blue is a chemical reaction that darkens the ferrous metal.

This probably overkill and perhaps not possible in your situation
(unless the chimney can be removed to a shop). :(

Stainless steel can be successfully powder coated..... clear or color
coat.

Didn't I say "try a sample area"? Do you know that it won't work?

My experience with bluing in the machine shop says it won't work, and a
bit of googling more or less confirms that, although I did just find
some references that say if stainless is acid etched it can be hot blued.

Gun bluing is not the same as bluing used in a machine shop (which IS
blue). Gun "blue" is black.

Sorry, if you don't believe me...you'll have to go to a gun shop! The
only thing in common is the name.

So GUN BLUE that is used in a machine shop is not the same as GUN BLUE
that is used anywhere else on the planet? I'm sometimes confused, but I
think it's you that's confused on this one.

I've never used this in a machine shop...but maybe you have!

The outer face on a triple wall chimney should not get past slightly warm to the touch unless the OP has a roaring fire. The sun sh8ining on it will bring the temperature much higher. I am sure he/she wants to hide the bright glare coming from a stainless chimney on a bright sunny day. Almost all the suggestions to date don't take into account that the chimney will be exposed to a wide variety of temps and weather, and can't be brought into a paint shop and then reassembled on the roof. A spotted chimney may look even worse than a consistently shiny chimney.

It happens that my triple-wall stainless steel chimney was in the category of producing glare. I chose to build/enclose the entire chimney in a wood-based simulated brick housing that from the ground looks like real brick, and does not reflect sunshine into any of my neighbors faces. I do have to paint the trim every 4-5 years, not a big deal.

I had to paint the lower part of my chimney that stuck down below the
ceiling. Mine is triple wall stainless too. I simply scuffed up the
outside of the pipe and sprayed it with the black paint used for repainting
woodstoves. It's a high temperature paint designed for that purpose. I
bought mine from the same place we bought our woodstove.

After ten years there is no sign of peeling or flaking. It still looks the
same as when I first painted it. Of course, that's indoors, I don't know
how well it would hold up outdoors.

I don't even have to see it; it does not look like brick. It looks
like fake brick.

Ditto. When we installed our wood stove (ca 1985) I used Metalbestos
insulated chimney which is stainless steel inside and out. That portion
of the insulated chimney below the cathedral ceiling is painted with the
same flat black, high temp paint used on the plain metal chimney
extending up from the wood stove. It's been painted ONCE and it still
looks just as good as the day it was painted.

Above the roof we did the same thing, only with Rustoleum, high temp
(for no particular reason), flat black and we've spray painted it about
four times during that same period. It really needs a recoat now but
it's probably been at least 12 years since I climbed up there (or had
the inclination to do so) to paint it. Maybe this year<g>

In any event, the coverage is still about 85%.

I did no special prep on the SS other than to wipe it down with whatever
thinner was recommended to remove oils etc.
