Yes correct tip. I even tried a larger tip to help flow and that did not work. It's like one pass is great and the next it shoots a ton of paint in a 2 inch circle like the someone went and manually changed the air pressure or something. 60 gallon compressor 25ft hose. Gun may just give an inconsistent spray pattern. Weird thing is my firewall which I shot first is great. Maybe gun wore out that fast. I clean thoroughly every time. Seems it shoots way better if the gun is held horizontal than vertical. What I cant get over us why even with so many coats is it not covering? That's why I wonder if it's a paint issue and not a gun issue? I did a lot of research and the paint had good reviews and is definitely not high end but not cheap either. I dont know anyone to borrow a gun from so I guess I will have to pony up for a better gun. Wasting time and paint is getting expensive. Thanks
