Spray Gun

I have tried a bunch of hobbyist type guns. Guys with experience and skill can get a great job from a crap gun.
I am not one of those guys.
So far my limited experience says this works great for filler primer.

I have a now discontinued devilbiss flg 3 that i spray base and have sprayed primer and rustoleum with. It did nto atomize the cheap clear I was using very well.

For one or two paint jobs I probably wouldn't buy it again.
For clear I use an astro lvlp. Unfortunately it is also discontinued but it is awesome at atomizing clear. I would probably buy whatever model replaced it and use it for base and clear if I was buying guns for the first time again.

I am struggling to get rustoleum to spray well but so far the 20 dollar harbor freight green hvlp gun has given the best results.

I try to keep a couple harbor freight purple guns laying around that I will use to spray thinned latex or oil based tractor paint on stuff like my porch or chassis or differentials etc.
