Iwata Spray Gun for Clear: Best in Class Results

This one’s a clear coat and basecoat workhorse. Most folks lean on the 1.4 mm tip, and for good reason; it absolutely delivers when it comes to getting that glassy, high-gloss clearcoat. According to Iwata, the 1.4 mm tip is ideal for that kind of finish.

That said, a lot of painters swear by it for basecoat too. Everyone’s got their own process for getting pro-level results. Some even use their Iwata as a primer gun; that can work just fine as long as your primer is thinned properly.

While some painters reserve theirs for detail work, repairs, or single panel jobs, most use the Iwata as their everyday go-to for automotive clearcoating.

And it’s not just for cars. Plenty of folks use these for woodworking projects and household painting. The gravity feed setup and low pressure help keep overspray down, which saves paint and leaves a softer, more refined finish. If you’re painting cabinets, this would be a solid choice.

Why Buy an IWATA LPH400?

Quality construction equals longevity.  You will get what you pay for here with a spray gun that lasts forever.  It doesn’t even weigh 1 lb (without the cup) so you’ll never have wrist fatigue or downtime.

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.
