Iwata Eclipse HP-G3 - Airbrush Guru

Iwata Eclipse HP-G3

Review and Opinion:

  • I’m a big fan of the entire Iwata G-series, to me they’re what Trigger Guns are actually supposed to be.
  • The HP-G3 in particular is a tiny spray gun.
  • The blunt needle means you can avoid tip-dry and it should be difficult (though not impossible) to clog.
  • The HP-G3 doesn’t use much air, so you can run it off a small airbrush compressor and still use all the fan pattern features.
  • As far as I’m concerned, the G3 puts the K-TH to shame. Of course, the K-TH is actually a little smaller so you can get into door jambs easier.
  • The G3 is perfect for background work. Don’t get carried away and try to paint a car door with it, but a helmet or motorcycle gas tank should be fine. You should also be able to spray tan or paint large special F/X on people.
  • There’s a nice little hook on the top of the gun. This is so you can hang it from a conveniently located bolt, screw, or rod.

  • Built-in Pressure Regulator
  • Adjustable Fan Pattern
  • Cartridge Style Air Valve Set
  • 4 oz Aluminum Steel CupI’ve never heard of Aluminum Steel–so I looked it up on Wikipedia. The summary is that Aluminum Steel is basically lighter than steel, more flexible than steel, and less corrosion resistant than pure aluminum. Oh, and it’s less expensive than stainless steel.

Outstanding/Common Problems

  • Clogs

    Unfortunately, every airbrush or spray gun still clogs. The blunt needle eliminates a good deal of that clogging, but the nozzle size is still small. If you run into problems run through the cleaning guides.

  • That’s it as far as I know.
