Adhesive letters for kegs

[kugeman]

Does anyone know of a supplier for letters/numbers that I can stick on the side of my kegs. Obviously I need something with a strong adhesive that can put up with some major abuse and stick to stainless. I've seen kegs with adhesive letters on the side before but these ones are a little more hardy then the type of stuff they sell at the local hardware store.

If it matters, I don't actually need any letters, just numbers. I'm putting serial numbers on all of my kegs and this seems like a easier way to do it then welding on stainless plates...

thanks...

How about a stencil set and a can of spray paint? You can even get a logo on there.
