Nut/bolt marking paint?

what is the paint like material (to mark a nut or bolt after tightening) used to determine if it has gotten loose? It is usually red, but I have also seen other colors.... can it be purchased commercially?

F-900 "Anti-Sabotage Laquer" or birdsh*t, aka Torque Seal.
Can be bought almost anywhere, Aircraft Spruce, SkyGeek.com, or from the maker Organic Products.
