I'm a c33,painting contractor. 75 gal. is a good day painting! I like a short extension on the gun, it saves the arm and shoulder. Is your tip aimed horizontal, or vertical?
LoL! Blew the packing out of my old graco near the end of the first day... When I went down to check it out I could hear a bearing making noise in the motor, also... and I was on a tite schedule...
SO, I bought a little 390 next morning on credit.
Just didn't want to deal with my big gas pump.
But there were other factors that influenced my decision.
390 is just a little bit too small.
Probably should have got the 395 or Titan 440i.
Now I'm at six pumps. Not worth making repairs to sell 'em, no one is buying!
Well Bigfish, on exteriors I once always used a 12" extension, for a tad more reach.
Got away from it, because we do many eaves w rafter tails.
The inside stuff, at least in this house was all cut up, with lots of short walls, too many closets and returns, and narrow hallways. No extension! I should have used one for the 10ft lids though.
..I usually leave the pattern flat (horizontal) across the gun. Spray in vertical pattern. Use a whip...
When using my HVLP I do switch tip orientation a lot, though.
...LoL! I'm playing hooky, right now. Should go in, but I'm going to wait and just do a couple hours this afternoon. Lacquer the front door before the stucco guys splatter it, so it's easier to repair!
I had a worker almost die using epoxies without a mask in a small work room. I fired him shortly therafter, figured anybody who was as wreckless needed to find a job where he didn't get to make decisions about his own health.
