I haven't tried it, but I read it on the internet, so it must be true. I'm staying home today, so I'll give it a try.

I just tried it with a multimeter set on 10 volts DC and a AA battery. No needle movement on any anodized surface I tried. The needle jumps to 1 1/2 volts on bare aluminum.

I don't think anodizing is an electroplating process.

I know about stamped on paint logos because I watch How It's Made.
