Well, in the process of weathering my latest build, I noticed that my old Thayer and Chandler Omni Matrix was not spraying all that well. I have Grex Tritium that is my go-to brush, but still use the Matrix for some weathering tasks and what I want to shoot small amounts of paint. I took the airbrush apart, looked at the needle and tip closely, and discovered this:
Looks like I need a new tip!

What mystifies me is that I have no clue how I cracked the tip (and, apparently, dented it). I'm generally very careful with my airbrushes.
Now I have to hunt for a tip online, as no stores near me carry T&C parts. Anybody know of any good online stores with free or cheap delivery in the US?
