Yea you are definetly not going to get a "smooth" texture out of the gun. I would describe it more of a webbed, look. Kinda stringy but not thick and gooey. You want a uniform spray pattern in that you don't want it to streamlined.
One thing I thought of though is that where are you located (in the country)? The reason I ask is that if the glue is cold, you'll have issues with it spraying. Try to let the glue warm up to a normal room temp, if possible.
I use both a pressure pot and cheap siphon feed gun.
