Noalox is for connections between aluminum to aluminum or aluminum to another metal. It is not a lube, and pretty bad for moving parts that rub because it will act like sand paper pretty much.
It's great for a mod like the Reo and the bottom of it's spring connection to the body. It was also good for the Reo's firing pin, because when a smudge was applied to a filed down pin it would fill in the pits nicely to prevent arcing. It's fine for the something like the Reo's pin because, it's exactly that: a pin like contact. Noalox dries up, and you can just put a new blob of it on.
When I was using tube mods, I tried putting Noalox on threads before knowing any better. I also read of people doing it so... Quick fix, but really bad idea over all. It's a complete mess on threads over time. It also contains zinc particles (I think), and they literally act like sand paper on your threads. Over time, your threads will just get rougher and rougher. Noalox is especially horrible for fine/thin threads.
Use what the hardcore flashlight people use for threads and o-rings; Use Nyogel or it's generic counterpart "Super-Lube." This will keep your threads smooth, tear/pit free, conductive, and also keep your o-ring nice and healthy so it doesn't break down.

Clean the threads with alcohol, apply the lube. Done. If you want to spend more money on it, apply some Deoxit gold after cleaning and before lubing. But simply keeping things clean and lubed is pretty much fine.
As far as Provape officially recommending using Noalox on the Provari's threads.... yikes.
