Hi Vince,
Since I have not had the opportunity to compare these two respective kinds
of Paint sparying Guns for having taken them apart to see the
engineering-mechanical-design difference, can you maybe explain them to me?
The 'conversion gun' is what, a regular one which has ( merely? ) a little
larger diameter metering rod
and a slightly larger oriface?
Or is there more to it?
Far as I recall, Binks, DeVilbis et all, pretty well always sold Guns for
various viscosities,
and or sold kits to adapt existing set-ups for being more effecient for
viscosities other than what their original metering rods and orifaces had
anticipated.
So...do you know? - what is actually different with these?
Best wishes,
Phil

I have used high pressure spray guns, a turbine driven HVLP and now today
for the first time, I tried my new Geil. The Geil is quiet-no turbine-it
delivers a lot of glaze where you want it and it is easy to use. I Like the
gravity feed reservoir which is translucent so you know how much glaze is
left. Giel says the gun has extra holes in the face that facilitate the
glazing. I can't tell if they deliver glaze, help disburse the glaze or
???.
I saw it demonstrated at Geil's plant and it works as well for me as it did
at the demo.

Hi Donald,
Was there any discussion about using the fan spray feature and not
using the fan air? What is your experience in this regard? It seems
to me that I can get it to put out a nice mist at a lower pressure
without the fan air on.
Thanks,
Gordon
