Touch up guns

[Yams]

I am sure there is already a thread out there, but I was wondering if anyone had experience with cheap touch up guns.

This is what I was looking at, but I was wondering if my dual piston AB compressor can run it. It says it takes 3 CFM at 50 PSI, but I would only be running it at 20 - 25. My compressor can supply about 1.4 CFM not sure at what PSI though ): Is it even a possibility?

Only use mine on a 15cfm
But if your compressor has a tank you can increase your capacity by putting a long airline on it ,acts as a bigger tank
