What kind of paint would you use to paint a paintball gun?

I used Krylon Camouflage colours for mine. They have a few different colours available. Or try Duracoat, its what all the "real" special forces guys use apparently.

Duracoat is expensive though. If you wanna run it through an airbrush get some automotive airbrushing paints. They should be durable to stay on a car, then clearcoat after.

I'll probably use spray cans, for nice thick coats.

Outfits like Bass Pro and Cabellas sell the stuff, last I looked in both bottles and rattle cans.

As Ross noted, places like Cabellas, Bass Pro Shop etc usually carry cammo paints and advertise them in their catalogs.  You might also check out shops that carry paint ball guns and supplies - A lot of them seem to stock the paints also - And if you have access to a military post (or have a friend who does - check out the Px or the clothing supply store - never saw one that didn't carry a line of camo paint in spray cans - and they're Mil Spec)

I'd go for a lead based product myself 

I wouldn't paint it, instead I would have it powder coated. Break down the gun and have the larger pieces powder coated. It will be more durable than paint.

If you can't and paint is the only option, then automotive lacquers are the way to go. You might find a body shop that will apply the base coat for you. The key is drying it in a very warm place for several hours. 

check out http://www.kapowwe.com/Merchant2/merchant.mvc?Screen=PROD&Product_Code=dc-urban-ps&Category_Code=&Store_Code=R  They have all kinds of different patterns and colors.  Kits generally run about $75 and have enough paint to do 2 rifles and a pistol (give or take).

I have a team's worth of Tippmanns to paint (A5s and X7s) and these are the kits I'm going with.

Somehow this is sounding expensive. Why not just get a roll of the cammo tape you put on your shotgun and when it gets beat up, change it.

Most airbrush artists these days are using Urethanes for this but they are a tad expensive.
