I Know SQUAT About Spraying Automotive Paint.

Ogre is right, those clamps are made for copper and cheaper. You could do the same thing as me by hanging a piece of wood down instead of all-thread and using the copper clamps and save some money.
I got my clamps from Home Depot and they are made for holding conduit. They do make them in copper but you'd probably need to go to a plumbing supply house. Here's a link to what I was thinking of using. There are various types just Google copper pipe clamp.

I did wrap mine very well to keep the metal apart:

And spent a little more to use these hangers so I could really fine tune and adjust the slope of the pipe to keep the water running down hill and not have any dips in the line for water to collect in when air isn't flowing.

Once again in this photo you can see the string line I ran to get the slope I wanted. I still hadn't wrapped the pipe in this picture. I'm an amateur, not a plumber, so I slip fit all my stuff together and then took it apart, sweat on the tees and/or 90's then wrapped the tape where the hangers went. Then I hung it all back up and connected the pipes with my couplings, twisted the pipes so I could get the tees/90's the direction/slope I wanted them and sweated the couplings together. Certainly a lot of extra steps from how a pro would do it but it came out good the first try. Well other than me forgetting that extra tee and the drop with the ball valve at the end.
But even without that stuff I was D/Aing on my car a bunch yesterday. And while my tank and separator had a some water in them from the compressor running the whole time I never got water at my tool.
My "shop" is probably a little bigger but space is at a premium, especially when working on something as big as a 66 Lincoln.

Huh? Why would you wrap the copper? I thought the whole point f using copper is that it disappates heat faster than black iron or galvanized. Why would you WANT to insulate it with wrap?

PS: I like those Vega Industrial Supply copper hangers but they look pricey. Not sure why I'll do but I do know about the issue of dissimilar metals, galvanic action and also just the wear on two adjacent parts when they vibrate so I'll be careful.

He's just wrapping the connection between the copper and the steel hanger. Different metals will react with each other and corrode.

Ah so.... I thought he meant he wrapped the entire pipe.

What Richs55 said is why.
