Ok... so sometimes you feel like a ricer... sometimes you are.... LOL


I have an old nitrous bottle sitting in my attic, waiting for it's return to glory... it's scratched and scuffed and looks like the fat Anna Nicole Smith after a cat fight with Oprah over the last twinkie.

I luckily have access to a powdercoating facility, but I've never done a bottle before. My bottle is an older 10lb NOS one, but I emptied it a long time ago.

I want to powdercoat it, a process which involves exposing it to an electrical current, then passing it thru an oven (750 deg F) for about 20 mins.

My question to anyone who may know... is this safe ? Do I need to remove the top portion of the bottle (valve) and if I do... how do I do it ?

Should I take it to a dive shop for disassembly or can I do it myself ?

Any help would be great...

i dont see why you couldnt the metal isnt going to melt or warp at that temp, but to my understanding powdercoating doesnt heat it to 750 but more like 400 max for a longer time?

yeah, sometimes not even 400 F , but def not 700 F, although im not sure if you can powdercoat that bottle or not. i wouldnt try though, unless you find someone that has already done it

the only thing i really see wrong with doing it is you need to be able to see the bottle certification stamp, powder coating will more than likely cover/fill in the stamp.

well you could mask it off depending on where it is

1) What exactly is the cert stamp for (forgive me... my engine was built for nitrous, but I've NEVER used it...basically a nitrous nOOb).

**I am not living in the US, so certain laws and technicalities need not be followed as long as safety is not comprimised.

2) As for the temperature...my company's oven can go to about 530 deg C (which allows us to apply different coatings) I'm not sure exactly what temp we bake the powder at... but 400 sounds low... but either way... w/e the temp... it's high enough to melt stuff... LOL

Now as for actually powdercoating the bottle... the ORIGINAL finish from NOS seems to be powdercoat, so I assumed it should be viable, the metal will take the powder for sure.... I'm just concerned with possibly taking off and re installing the valve portion to ensure there is no nitrous in the bottle.

Any more info please ! I'm going to be doing a set of valve covers and intakes soon and want to do my bottle one time....

I powder coat many items every single day.

Temp should be no higher than 480*

i dont see a problem coating it, as long as the valve is OPEN to vent any unwanted pressure (no ****, eh?)
