Assembly lube for camshaft.

molybdenum disulfide...it used to be in many cam kits but cost may be a factor for not seeing it as much as before....I have a huge container of the powder and mix it as needed when needed...in dry powder form you can store this stuff forever..a bit costly but a little goes a long way...you can source it on e-bay....nothing compares to the very shear protection this stuff provides...
