pressure regulators for airbrushing

Oops, forgot to sign the post on using Nitrogen.

I have heard that Nitrogen is great for painting as the water based acrylics do not tend to air dry between the nozzle and the painted surface.

Nitrogen makes up about 3/4 of the air that we breath if my memory going back to college is right so it is environmentally friendly.  I also think that Nitrogen is extracted from the air and compressed for sale.

I keep planning to buy a Nitrogen tank. Picked up a Nitrogen 2 stage regulator off EBay some time back at a big savings.

Not to miss the fact that the fermentation process gives off CO2 as a waste product. And while I'm at it, remember that all carbonated refreshments (adult and otherwise) contain dissolved CO2. I could go on, but I suspect that the good Dr. Smith might object to my beating of a dead horse...

OK - before this gets too out of control, I would like to point out that if you get a CO2 system, you can also use if to dispense beer from kegs, as I do, which is a serious plus!   ;)

I would like to add to this conversation about the use of CO2, a recognized greenhouse gas which is increasing in concentration in the Earth's atmosphere.

The use of CO2 would seem reflexively to be bad, as global efforts are needed to decrease CO2. However, most industrial bottled CO2 is captured from natural gas extraction as a waste product. This CO2 would end up in the atmosphere with industrial use or simply left ignored.

As long as we produce and use natural gas, we will have CO2. Avoiding using CO2 for painting freight cars won't make a difference in the climate.

If you guys are going to complain about CO2 pollution why don't you also complain about the ozone created while running trains or the plastic pollution caused when sanding or trimming the flash off of your epoxy and plastic models. 

This is not an Al Gore Global Warming site but a Model Railroad Hobby site!  Lets keep politics out if it!

In some locations this is true. In others it is extracted from the local atmosphere. then it would be a wash as afar as the earth is concerned.
