Thanks for all the replies guys. I really wish we had Harbour Freight up here too....would save me some headaches.
I will have to check the settings. I am not using a regulator on the gun, but if I remember, the pressure regulator on the compressor was at 120.(?) Seems high to me, but it's a rental unit, and I don't use compressors much.
I got the namual for it online (Makita 700), and cranked the regulator all the way to let the most pressure through. The spray seems better this morning, but it is only spraying a 3-4" diameter spray.
I'll try to get back to you with some more settings and possibly the gun brand.
Thanks again, guys.
