I am working on painting my first car. I originally purchased one of the 43430 guns from Harbor Freight but the compressor I have access to isn't powerful enough to run it. The 43430 requires between 10-14 cfm while my little compressor puts out between 2.8 and 3.7 scfm (I don't know if scfm is any different than cfm). I turned the air flow up to 90 psi at the compressor and 50 psi at the gun but it would only spray a really fine mist out. Too bad.
In the mean time I have been using an old Brinks syphon feed gun. It is old but I have been told it was a quality gun at one time, and can do the job. Unfortunately for me the tip of this gun is smaller than the minimum 1.4 tip I need for my SPI single stage. My next thought was to get one of the standard gravity feed guns from Harbor Freight (model 47016). However, I just checked the HF website and it says this gun requires 6 cfm.
So I have two questions. First, will my compressor not be able to run this gun either? And second, this gun has a 1.5 tip, will this be ok when the paint I am using calls for a 1.4 tip?
