Yea that thing would look superb with paint to cover dis-coloration and other "stuff". You might know this, but I would suggest Krylon Fusion, just look at how <a href="http://www.spudfiles.com/forums/viewtopic.php?t=221&">THIS</a> gun turned out with it. Nice gun!

Krylon Fusion paint is the best paint for PVC. I suggest trimming down the plexiglass while your at it. Nice job!

I have the same to say... The gun looks very cool, man that's a wierd kind of sprinkler valve, I haven't say thoose anywhere...

If you paint it, it will look like a million dollars... good job, I love the polycarb. idea

The valve is just a standard right angle 1" valve I found at home depot. I don't know the brand name but it starts with an "N". I like the valve; I had it electric for quite a while. I recently modified it for pneumatic it must have quadrupled the gun’s power. I'm going to try to paint the gun with some Fusion soon. It's kind of showing its age as far as all the discoloration. As for the polycarb I’m not going to cut it down. It serves as a stand as you can see in the pics, plus it’s awesome for aiming as it’s semi-transparent. Once again thanks for the comments keep them coming! :D

The valve is just a right angle 1" modified sprinkler valve from Home Depot. It was actually the cheapest one on the shelf but it’s been awesome.

The 90 degree angle thing is weird to me, all of the ones I see are inline - in and out

Like mine:

Or this:

PS: Your gun looks %400 better with a paint job, that thing is an absolute beauty, I mean that thing is REALLY respectable now, in fancy talk, but to put it shorty, dam that thing is NICE.

I just liked the 90 degree valve. I think it might have slightly better flow as well. Check out these pics and see what you think:
