It seemed like the advantages were mostly in my mind, while the disadvantages (dirty to apply and deal with, cleaning cycles weren't much different) were enough that it just wasn't worth it. Mostly I just got lazy, quit applying it and didn't notice any difference, so I left it behind.
Then I tried UBC, which seemed to work better as far as helping out with less cleaning, and was a one time deal. No more moly for me!
