the new EZLs used to come with the paste already on them, and a protective wax paper or plastic wrap was used to keep it from making a mess within the box.

now it comes in a little syringe, but you still cant buy the compound from the dealer.

Radio Shack has "Heat Sink Compound" also called "Heat Sink Grease" part number Model: 276-1372, Catalog #: 276-1372
