Spraying Behr house paint through a Sata Jet 100B P. The P stands for polyester. which means it has a very large tip. 2.5mm, to be exact. Thin your paint 10 percent with water. You could thin a little more if you are using a smaller tip. However, most paint manufacturers only recommend 10 percent. I have used this trick many times, and it turns out like glass!
Oh.... at the end, clean your gun as usual. I remove the air cap and scrub the entire gun with a nylon brush, then clean and spray rubbing alcohol through it. I only use the pps cup with water to flush when the gun isn't spraying the way I like it or flushing at the end.
Thanks for watching!!
