I have found this on projects using XL pipe as the electrogalvanized
coating is so slick that any cutting oil residue seems to leech down the
exterior pipe wall and finally collects on the deflector eventually
dropping to the floor and making a spot on the carpet.

I would lean toward exposed pipe dope. It separates and must be stirred
occasionally. The oily substance I have found on sprinklers looks just like
the oil in the compound. If it were from the fittings, I would almost
certainly think we would see water. Since most helpers (I in the day) use
the glob/brush method, I would think there is enough outside the threads to
separate over time. Even years.
