Window markers? (Writing on car windows)

[ronpaulitician]

Saw this suggested on a RP YouTube comment:

use window markers to write "Who is Ron Paul?" or "Ron Paul R3VOLUTION!" on the windows of your car.

Quick search for "white window marker" online left me scratching my head. Which one to buy?

Any suggestions? I'd love to get a white and red marker.

You can even go to a local party supply store and buy them.
