Here is my perspective on the whole issue :-
.
The first question is -
Do these spray guns produce acceptable results for the job in hand?
If I had to paint a Rolls Royce, I would take the car to a professional painter of Rolls Royce cars with a known reputation for quality work. I would not consider an amateur job with a cheap spray gun. For painting a CNC frame I would probably use a disposable foam brush anyway.
.
The second question -
How valuable is your time that you would spend cleaning out a spray gun?
Generally, when I do a job, I carry on until I am finished (not only the job, but me as well) and am too knackered to do anything but a functional clean of my tools and equipment. So the value of my time increases massively when I am tired.
.
Thirdly -
How much does the solvent cost?
Not only in £s but also in environmental terms.
..
The final issue for me is who do I trust? A member of this forum who, for some years, has been giving the sound advice of his experience OR someone whose first post on the forum descends to a rant in a short time.

The title of this thread is; "Best cheap Spray Paint Guns for DIY CNC builder or small workshop"
With key words being, "Best cheap"
Boyan is therefore not trying to say these are as good as 'expensive' spray guns but rather, these are the best he's found that are 'cheap' spray guns.
So if the reader is looking for a cheap spray gun, one of these is a good choice but if the reader wants a better spray gun then look elsewhere.
As cropwell said, the price of solvent is an issue now, gone are the days when you get a gallon of parafin at the local shop.
That's why I buy a pack of dirt cheap paint brushes for non critical work because it's cheaper to bin them than clean them after use.Last edited by EddyCurrent; 19-02-2018 at 06:22 PM.

I bought 25l's of Thinners (We do a lot of vinyl removals on vehicles it's a bastard to clean the glue off) was cheap try car parts suppliers, but normally I chuck the paint brushes anyway as I use £land ones ;)
Is Paraffin the same as kerosene? In which case you get a gallon of it from any local fuel supplier for a few pounds it's often called 28 sec.Last edited by Desertboy; 19-02-2018 at 07:25 PM.

If you didn't buy it from China the company you bought it from did ;)

Paraffin, Kerosene, White Spirit (and many others) are all basically the same straight chain hydrocarbons, with a varied mix of molecules each with 9 to 17 carbon atoms. Any more it goes to oils and waxes, any less it is petroleum or gas.
In the 60's, working in a lab, there were gallons of ligroin (7 or 8 carbon atoms) we never used. A lot of it went into my petrol tank
Cheers !

I very much suspected that would be the case. I have ordered the little gun. You beat me to a similar post (pipped me at the post
).
In one of the criticisms of the K3, it was stated that the upper screw adjuster was for 'paint volume', whereas it is for the air volume, adjusting the shape of the cone of paint. The F75 has a fan spray pattern.
My K3 is on order.

I bought 100 foam brushes for £10 so at 10p a pop it just ain't worth cleaning them and they give a good result with any water based paint, PU or enamel paint. They are not recommended for French polish but they are OK. I would not even try them with cellulose, but I just don't use that any more. Two pack is probably a no-no.
