I've seen people paint their armour, sometimes with a coat of arms or other image, and I was wondering what type of paint you would recommend to do this. I'm looking for something durable and inexpensive, hopefully with a wide range of colours. I have also seen historical examples of armour that seemed to be painted.

Look into "milk paint".

Based on my shield-painting experience... milk paint doesn't like to stick to metal very well at all. It'll probably require some kind of a base coat, which may or may not be available in a "period" formulation (if that's a concern for you).

Just as a heads-up =)

Weren't a number of shields and helm crests "primed" with gesso (some kind of plaster-like substance) before the paint was applied? That may be the key to getting the paint to stick.

Nathan,
For my armour based painting projects, I use Linseed based oil paints. It is historically correct and it adds a nice authentic texture to the piece as well, it's also fairly inexpensive. The only problem with it is that oil paints are very slow drying so you will have to leave to the piece alone for a long time after you finish painting.
Depending on the type of oil paint you get and how thick of a coat you put on the piece it can take up to a few days to even a month or longer to dry. Another problem with it is can scratch off so prepare to touch it up now and again.
To prime the metal for painting I just take a 100 grit sanding sponge to it then paint and I haven't had any problems.
You can also use Galkyd slow drying medium on it the steel then after it dries apply the paint, but I haven't tried that.
Here's pictures of the Sallet I'm working on now after two coats of black oil paint. After this coat dries I'm going to do give it another black, then on to some yellow detailing.

I have several pieces that I'm interested in painting, so I'll try a number of your solutions guys. I like the idea of the oil paint, and in your pictures the helmet looks really nice, is that an open faced sallet? I'm not planning on painting a large portion of my various armour pieces, just enough for a family coat of arms and such. Thanks for your suggestions!

Yep it's an open faced sallet, wasn't originally but it's a loaner for my living history group to go with a lower class kit. That and the visor wasn't that great and kind of dangerous to boot. Good luck on your projects.

To protect the inside of my gorget, I used gloss Rustoleum (rust-resistant paint). It's lasted at least 10 years now with only a few chips here and there. A matte finish might be better for the outer surface. I decided to just let mine patinate on the outside.

In one of my metals classes a girl applied gesso to sandblasted copper, so I'd imagine it would work for steel as well.

If it does not have to be historically correct (chemically), alkyd epoxy enamel based paints (rustoleum is an epoxy based example) are a general class of paints that adhere to clean or primed metal. You can get it in a variety of finish glosses and viscosity/ thickness applications. Non stainless structural steel and piping are generally painted with this type for indoor or outdoor purposes. I believe Wattyl makes and distributes it in non aerosol cans for hand brush application.

I haven't seen any evidence for medieval milk paints in any of the surviving manuals, or in any conservation reports.
Medieval and modern oil paints often used linseed oil (extracted from flax). Linden oil would be from a lime tree (also known as basswood).

Hey Mark I made a typo in my post above I meant to say I use linseed rather then linden seed. I don't even think they made an oil paint with linden seed as the drying medium.

Messrs Chmielewski and Eversberg: thanks for the info. Will file that away for possible use on some future project. And all apologies to the OP for the partial threadjack!

I'll rephrase that: I haven't seen any evidence for the use of milk paint between 1300 and 1500. The surviving painter's manuals describe egg tempered, size tempered and oil tempered paints. Analysis (mostly of paintings on walls, canvas, and wood supports) seems to agree with the manuals.

That's true, Mark. I do know earlier sources do mention milk paint, however. I've not dabbled with the stuff myself.

What is "size" tempered, by the way? Not heard of it.

Size = animal or hide glue. It's called so because it's usually used for "sizing" the painter's canvas - making it less absorbent and protecting it from harmful oils. I think hide glue paints (technique is called Distemper size) were described in some manual to be used on metal.
