Re: Buying inert gases (argon, nitrogen, et cetera) in lieu of Bloxygen.

I have a can of Bloxygen and use it sometimes when closing up a can if I'm in a hurry but usually I'll flow argon from my MIG welder in since it's a lot less expensive. Nitrogen will work but it's less likely to me that all moisture will be excluded when using nitrogen since the nitrogen is only about 0.5% heavier than air. Argon on the other hand, about 40% heavier than air, will stay in the can when open for quite a while if there is no draft.Most welding supply shops will have tanks of argon available. An "A" bottle will provide enough for many paint cans but you do need a pressure regulator.PhilBrian Phillips wrote:
