I've shot por 15 with a gun plenty of times, although I have several spray guns so I just used one of my cheapie astro guns. Just make sure you clean up the very second you are done spraying and you'll be fine.

From what it sounds like you really don't need a full size gun. I would go with the Sharpe Finex with a 1.0mm tip (fx100). It can be had for around $80-$100 or so and it works very very well. Pretty good at laying down metallic and pearl colors as well.




Unless you will be regularly painting large panels, you really don't need a full size gun. The touch up guns allow for more control and less overspray on everything. They also use a lot less CFM than full size guns (I think the fx100 only uses 8 cfm or so?) so you don't need a 60 gallon 6 hp compressor.

Astro also makes some decent cheap guns, but keep in mind that you can't get parts for a lot of their guns. You WILL eventually need to replace parts.
