I have sprayed mostly oil base with it but have sprayed some latex and didn't thin it. But most of the time if I spray latex I will throw a splash of water in just to thin it a bit, while the gun will shoot straight latex I figured a little thinning couldn't hurt and would make it easier on the gun. I did use floetrol and penetrol accordingly with the latex and oil base paints. I really like them, they extend the drying time and the paint flows out really smooth. But if the latex is to thick and not spraying good you can add a little water to thin it out.
I like the gun and it was fairly easy to get the hang of. You have to have a decent air compressor, I have this one http://www.homedepot.com/h_d1/N-5yc1...&storeId=10051
and it ran pretty much non stop but got the job done. It worked but a bigger compressor would have been ideal. But I would think a smaller compressor would work but you would have to take little breaks to give the compressor time to catch up. Also need to have dry air, I put a good filter/water seperator in line. The air also needs to be regulated way down, I think for most of what I did it was around 30 PSI with the trigger squeezed.
I went to the local habitat restore in town and bought a bunch of cabinet doors for a dollar a piece to practice on. If you have one in town it is a good place to get cheap items to practice on. It takes a little to get used to adjusting the gun. Also make sure you strain your paint threw a filter when you pour it into the gun's can, I bought a pack of 100 at harbor freight for pretty cheap. It took me about an hour to play around with different settings in order to get the paint spraying the way I wanted it.
The gun is fairly easy to clean. For latex I just empty the can and fill with water and spray into a bucket until it comes out clean. Then take the gun apart and use a spray gun cleaning brush kit I bought online to clean the gun good.
I like the gun and use it mostly on trim and doors when needed. Meanwhile my airless has spent the last few years sitting in the corner of the basement collecting dust. I've used it a handful of times and it works great on brand new drywall like finished basements or if I ever build a new house but for most things it's just a pain.
