Best cheap Spray Paint Guns for DIY CNC builder or small workshop

[Philipp]

Let's just say, I'm always sceptical of people who join a forum, and then only post on a single topic.

No problem sir! PLEASE go ahead and purchase one of these Chinese-made K3 or F75 crap sprayguns. If you manage to disassemble parts (as shown in the above mentioned diagram) and clean them properly, I PROMISE to send you the amount you spent for purchasing these Chinese-made copies. On the other hand, if you also find that it is impossible to extract needle and spring, would you forget your ego for a moment and publicly admit that I was right? Please make my day and go ahead to buy. After all, you only have $20 to loose and feel tricked and stupid (like I did) by Chinese sellers. What do you say? Sounds fair? Do you really need to get tricked by Chinese sellers first to be convienced that these cheap HVLPs are useless?

From experience, that tells me either the poster has an axe to grind for some reason, or they have an ulterior motive/vested interested.

Please Mr Sherlock, please tell me ONE reason (ONE only) I need to say lies to you. Give me one reason for having ulterior motive/vested interest. I am just trying to save you money you silly! I am just shouting loud "...I've been tricked, I was fool and purchased these cheap Chinese-made HVLPs. Do a favor to yourself and do NOT buy...". Where is the negatine on trying to warn fellow hobbyist? Where?

Flushing works for me, but then some peoples idea of flushing is just running a little bit thinner/cleaner through. I always flush until I'm getting pure thinner/cleaner out, with no hint of colour. Then if it's the final clean, I'll fill it with thinner and let it sit for a couple hours, before giving it a final clean out.

Sir, I paint for more than 20 years. Never seen a paint (water-based, enamel, lacquer, epoxy etc) gets away with "just a flush". Ah, keep in mind, that my painting tools (airbrushes, sprayguns etc) are SHINING like new, even if I use them for 10+ years! And they are look like new, because I always clean every detail after use. On the other hand, the picture I saw earlier (click HERE) showing Boyan Silyavski's tools, they are dirty and obviously never care about them - typical sign of no proper cleaning and maybe not cleaning at all! Are your HVLP sprayguns also as dirty as his? More dirty maybe?

If it was to block, I'll just spend another £20/30 on a new one.

We all do have expensive tools on our bench. Tools that absolutely worth the money spent! The reason for all this, is the enthusiastic review for a product that is completely useless, and THAT should ring a bell for you all! WHY someone sends an enthusiastic review for a low-cost and low-quality product? Why? Hmmmm... any ideas? Any "...ulterior motive/vested interest..." (as you previously said)? Any?

Honestly, I would prefer to offer these $20 money spent to a poor guy, instead of purchasing the Chinese-made sprayguns. Maybe the worst purchase ever for me. And what really bothers me is that (for some unexplained reason) some people still insist that the Chinese-made less-than-$10-worth sprayguns are "great"! Well, no - they are not. Sorry!

Long story short. I asked user Boyan Silyavski to show a picture of his Chinese-made HVLP sprayguns completely disassembled as shown in the above mentioned diagram, as they should. What presented so far, was a picture of dirty sprayguns with obvious paint remnants - and that is a sign that clearly says that Boyan Silyavski's sprayguns are also impossible to get disassembled - just like the ones I purchased.

Make that 5 more times...

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.

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.

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.

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

Well you've obviously never used my Tar & Glue remover best in business.!!

After reading Boyan's post I order both models that he recommended.

Claiming that a brass nozzle cannot be removed from an aluminium body spray gun is hilarious.

Here is what I've got. I haven't used them yet but they look good manufactured for 10$ and 12$.

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.
