i dont use noalox

I don't use Noalox either but that doesn't help the OP. :)

Noalox is a grease type product. It will not dry out in a short period of time. You can apply it and wait till it dries out but there is no need & it might be quite sometime. ;) Just wipe the old stuff off before applying fresh Noalox then vape away immediately.

lol I thought that two but figured everyone gives their 2 cents online :)

The only reason I'm asking is that a lot of the photos I have seen of the firing pin, it looked like the noalox is dry but I'm guessing its just the way it looks. lol and yes it takes QUITE a long time to dry. I tried earlier when I washed it. Came back few hours later and said oh it looks dry now, hit the button and it was still wet inside.
I have has no issues since I had my massive short a few months ago and did a rebuild but just wanted to know what others do.

Yup. Noalox is non-conductive so it's okay to leave wet. It's 20% zinc dust by weight and works by removing any existing oxidation (that's the zinc part) and protects by keeping air and moisture out to prevent further oxidation (the grease part). There are some conductive greases out there but they can be pricey and I'm not sure of their effectiveness for our application (anyone else tried 'em?).

Talking about expensive grease. I used to work on Audis for 12 years, we used to use a special grease for wiring harness repairs and control module plugs. The parts manager used to yell at up to "USE IT SPARINGLY" Found out later it was $80 for something the size of a travel toothpaste tube lol.
I stole a bottle before I left, guess I should go in the basement and go through my old stuff to see if I can find it.

Reading from the bottle
"Promotes good ground continuity"
To me that sounds like Noalox is conductive. If it wasn't, wouldn't it block "good ground continuity"?

Marketing semantics? It could also mean it promotes good ground continuity by providing a clean contact area. Folks will read into it whatever Madison Ave. suggests. I think if it were truly conductive it would be specifically mentioned in the product literature.

We had a discussion about this a few months ago and short of being able to measure resistance through the Noalox (I tried) or measuring voltage drop with it applied (we did) I can only turn to the Internets for it's infinite wisdom regarding all things unknown or questionable or iffy.

..couldn't find the post but I still have a few pages bookmarked.

and

No more car battery terminal corrosion! or "The 3 types of electrical grease and their applications! | Page 2 | Hearth.com Forums Home

As you can see there are just as many "for" as "against". At best Noalox is mildly conductive but I wasn't able to measure resistance across it even at very short distances and there was no change in voltage drop with it applied and in fact went up when too much was applied.

Penatrox on the other hand is billed as being electrically conductive (e.g. acting as a bridge between conductors) and only contains 15% zinc dust. But I don't have any to measure at the moment.

(For the record I also experimented with Arctic Silver thermal compound and that didn't improve conductivity either).

Noalox is indeed non-conductive. Take your meters probes and touch 'em together, .03>.04... that's the resistance of the leads. Now stick the probes onto a tub of Noalox... non-conductive. Now touch the probes together, .02 How is that possible? Much like the thermal paste used to mount a CPU to a socket, Noalox fills the microscopic pours in the metal allowing for a more positive connection. I also find Noalox to provide an beneficial anti-seize barrier allowing ease of disassemble.
Apply thin and sparingly, nothing more than a coating. Noalox; not required but IMO it definitely has it's advantages.
