Black touch up paint for Canon lenses and camera bodies?

I know that white touch-up paint exists for L-series telephotos, but does black touch-up paint exist for black Canon lenses and camera bodies? My 5D Mark II and 7D have a few scratches and such on them, and while the bodies are fine, the paint has worn or scraped off in a few places and I wanted to fix them up.

If there isn't anything official, is there some unofficial way to touch up the paint jobs? A similar color of enamel paint or nail polish or something that's close?

Black permanent texta should do the job.......

I've found Artline Paint Markers are a closer match as they don't have a tinge to them.

Anything sold in the US that is a close match to the camera body black?

I got some touch up paint that is specifically for metal lawn furniture. Worked great for small chip like places. It was a generic from a hardware store and came in a little bottle with a brush, it was enamel based.
