Iwata Spray Gun for Clear: Best in Class Results

Clear coat and basecoat workhorse.  Most folks rely on the 1.4 mm tip and it really delivers on the promise of fantastic clearcoat results.   According to Iwata, clearcoat is the perfect use for the 1.4mm tip. 

Others swear by it for basecoat; everyone has their own way of getting pro results. Some painters use their IWATA as a primer gun, which could work as long as you’ve thinned your primer down enough.

While some painters use it for strictly detail, repair or panel work, most use their IWATA spray gun as their go to gun for all their automotive clearcoating needs. 

Some folks even use them for woodworking and painting around the house: the gravity feed low pressure delivers less overspray which reduces paint waste and leads to a softer all round finish.  We’d definitely recommend it for painting your cabinets.

Best Settings for Your new IWATA Spray Gun

The fluid settings controls are easy to access and adjust as are the fan settings.  There are even numbers on the knobs so you know how much you’ve dialed it in. 

For spraying clear, its recommended to try winding your fan control out all the way and then dialing it in 2 full turns.  

For fluid, wind the knob on your IWATA all the way in, then out 2.5 – 3.5 turns.  The temperature and your spray environment both inside and outside the booth, will affect the fluid setting you use. 

You will have to experiment and find the right setting within the recommended range.

Set your air pressure regulator about 2 bar (should be about 29 PSI)  Anything less than 2 bar and you will see some orange peel results because the pressure it too low and the paint isn’t being atomized correctly.
