Fire extinguisher tank

Good idea, anything else I could do? I think I'm putting paint in it soon anyway but I might not... I don't know yet.

I am not sure about yours but all my fire extinguishers are aluminum so the whole paint thing is not that necessary.

Yeah mine is Al but won't Al rust?

It will corrode eventually but aluminum resists much better than steel because its oxidation is tough and stays on.

No, it doesn't "rust" (although, being pedantic, rust is specifically oxidised iron). The oxide coating that forms on aluminium is protective.

Basically the top few molecules oxidise (very fast, given aluminium's reactivity), but then that top layer prevents oxygen getting to the lower layers.

So there is no need for that valve thing we were talking about or coating the inside with paint?

I guess it wouldn't hurt but its not critical.

no need for that valve thing

well it won't corrode but water will condensate inside the tank... if I were you I'd just mount it upside down

I can't mount it upside down:

New epoxy is curing. I used two part syringe type, slobered it all over where the tiny leak was a stuck the vaccum onto one of the 1/4" ports. There was no noticeable amount of epoxy being sucked into the leak but who knows, maybe this will be the final time I need to try to seal it. How long should I wait to test it? The package says 5 minute but I don't know if that is cure time or whatever...

ohh well...

I thought you wanted to use it as an air reservoir and that it is much larger... you won't have any problems with it

Mine is called 5 minute epoxy but the back says 2 hours till total strength, Id give it at least 2 hours.

OK I'll give it overnight just to be safe.
@Poland I think I already mentioned that it was a bbmg tank
