I want to have some barndoors that look like they are made of copper.
What kind of treatment would work for this?

Cheers!

Dear Ned,

Don't know the show or size of your barn doors in question, but if they
are already being/have been built, Krylon spray paint has a full line of
metallic paints of every kind, including copper, gold, silver, etc. With
a coating of good metallic copper paint, an added sealant of clear spray
lacquer, varnish, or polyurethane over the copper paint will give a
realistic metallic sheen to your finished work. Just be aware that there
are many paint companies that supply these types of finishes. Go online
and start searching.

Others on this NG will have good ideas about paints and treatments, so
consider their ideas as well. There are some very skilled artists and
scene shop technicians here who will have great suggestions for you.

Reagards,
Bert

If they are to be used as barn doors with instruments instead of for the
look I would be careful of painting with anything other than a "high heat"
paint.

Copper plating?

Electroplate copper be handled by anyone that does chromium plate
relative to price of copper sheet might be worth exploring.

I want to use these barndoors on a four-cell mole light, so I am
thinking the barndoor might be the size that would fit on a 10"
fresnel or so...I like the idea of spray paint, but there is the heat
issue. I will be using the barndoors as a "look" rather than to
actually shape the beam so there's that. Copper plating would be
great, but would that be insanely expensive?

Thanks for the replies!

WEll you can do it yourself, but you can just buy roofing copper, make  
your own & spray the inner leaf black. Heats not a huge issue with spray  
paint.

Here in the states you can buy spray paint rated for high temperatures.  You
sometimes see it as "stove paint."  It is easiest to find in flat black but
in comes in a variety of colors.  I never checked for any of the metalics
but I bet it can be found.

Thurmalox makes High-temperature paint in a subsatntial range of colors.
They have one called copper (although to me it looks a bit to pink to
look right, but they also offer a "metallic brown" "rich metallic brown",
"metallic mahogany"  and  "russet" and "goldenfire brown". I suspect one
of the 6 would look sufficiently coppery for Ned's purpose. At worst, he
might have to lay down a base coat of one color and overspray with
another.

Copper is first part of chrome plate, copper then nickel then chrome,
hence elctroplaters will do it, dosent need labour intensive polishing
in between plating keeps cost down. Copper is riding high as a

Might get away DIY with just contact plating:

Spray paint might stand the heat , but some types might flake with the
metal expansion.Big differnce on an MR16 to 5kW fresnel...

Just out of curiosity, what is the application that calls for copper barn
doors?
