Re: Air Spray Guns
I always thought suction and gravity guns were the same. Only the gravity gun was better for flat surfices like bonnets and roofs etc, because the pot wasn't in the way.
They run between 40-50Psi, depending on how much paint you apply in one sweep.
If this is a one off job, it would be easier to hire a gun, regulator, hose and compressor.
You shouldn't need a cleaning kit for the gun. Run thinners through the gun, pull it apart and wipe any paint away.
If you do hire it, the shop should tell you how to use it correctly.
