Painting old radiators
The rustoleum paint will work fine for a radiator or two. If you have access to proper spray equipment, you can mix your own by mixing powdered metal with "bronzing liquid", clear automotive lacquer, or just oil. The drying oil (linseed or tung) is the traditional approach and yeilds a beautiful, non-glossy metalic finish.
Powdered metal is aluminum and various bronze colors is available from US bronze Powders, 516-485-5544. It is also available from better paint stores, art and pottery supply stores.

Obligitory warnings: spray painting is dangerous. Do it with plenty of ventilation and wear a respirator and protective clothing. Polymerizing coatings can spontaneous combust. Allow all rags to dry flat and/or soak in water before throwing them away.0 -

Are those the REAL bronze powders? I've been using ones that are actually mica and they seem to work very well. I do think though that my "copper" "bronzing" contained powdered aluminum (or something) in addition to the mica as it mixed VERY differently than the rest.
When I tried to find the actual powdered bronze over the web couldn't seem to find a source in anything but industrial quantities. Also read that in raw state, powdered bronze is EXCEPTIONALLY damaging to the respiratory system with one good inhaled "dose" causing permanent damage.0 -

Yes, these are real bronze powerders and sometimes mixed with aluminum to acheive a particular color effect. Bronze itself is a pretty generic term and includes a multitude of alloys copper with tin, zinc, aluminum, lead, magnesium, etc.
I am not surprised that it is bad stuff but I don't think it is overly dangerous. Here is a link to one suppliers MSDS for it. It basically says don't breath or eat it but it is not especially alarming.

HEPA cartridge on a respirator is recommended for any finely powdered metal, if using a solvent or drying agent, back the HEPA up with a black organic vapor cartridge combo. Avilable from the Direct Safety catalog, or from most distributors.0
