I am posting this for M18x owners that want to disassemble their machine but do not know how, or they are afraid of it. In this video there is a demonstration of the proper technique to apply Coollaboratory Liquid Ultra thermal paste.
I apologize that the narration is somewhat out of sync with the video. The original audio is poor so the narration was dubbed after the recording.
