Campbell Hausfeld HVLP Paint Spray Gun —
Let me get this out of the way first. This gun works(worked) really well.
The problem is the cannister lid. The cannister attaches to the gun via a weird flanged nut that cannot be removed. Well, that section of the gun is too fragile. Mine broke after one use. I dropped the gun and it landed wrong, so I suppose it is my fault, but if the mechanism was better built, it would not have broken.
Now for the worst part. You CANNOT buy just a replacement dip tube with the nut on it, you have to buy the entire cannister assembly, which costs about 90% of the price of the entire gun.
So, in summary, it is a really decent gun, and it will serve you well if you are extra careful with the unit. I guess I would say it is not built for heavy duty work, if it can't a single drop from normal working height.
I will likely buy another gun, and just white glove it every time I use it.
