HVLP?

I use quite a few paint guns.

Most of the time if I am just shooting brackets, a fender, smaller stuff I use the purple HF spray gun, it shoots fine.
Clean it with about a 1/2 pint of thinner and go on, I keep a coupe extras on the shelf, when they start spaying like crap, toss them and grab another.

For a primer gun I like the green HF suction gun, it has a larger tip, and sprays a good pattern.

I do have a nice Anwest Iwata LPH-400, its a sweet gun, but I use it mostly for overall paint jobs.
I really don't use it a lot of the time, because of the cost of the gun ~$500.00, I am super anal about cleaning it, I bet I use 1/2 gallon of thinner to clean it each time.
