Two biggest problems with WL are, it evaporates over time in a bottle, to the point where the liquid it's suspended in becomes more of a slurry,(not really a problem if you use it *regularly, my bottle would sit for 6 to 8 months at a time).
Don't ever get it on the mating surfaces of your Liner Locks it can cause the lock to slip and fail,(it's that slick) this also applies to other lubes and Liner Locks.
I still like this product and I use it on my lockbacks and slipjoint exclusively, one last issue, I wish they could do something about the smell. :barf:
*What I meant by that is, if you use it regulrly it will not evporate faster than you use it, ya know what I mean?
