hey guys recently bought a satajet 4000RP 1.2 fluid tip.
having a big issue with its paint consumption.
this is my clear gun only. full fan, full gun trigger pull and inlet pressure at 2.4 BAR
on a complete, (no door jambs) its using about 7L (just under 2 gallons of clear)
and thats only 5 coats of clear.
what do you guys think it could be??
Only 5 coats of clear :blink:
Try 2 and see how you do with that 😉my devilbiss gti pro or my iwata supernova will use half the amount of clear as my sata 4000 but the sata sprays so much better.
i just want to know why it uses so much material.
i shot solid in it before, 3 doors, 2.5L and just got coverage. didnt have enough colour to finish off the vehicle.
For starters you are spraying at too high of an air pressure,max on the 4000rp is 2.2 bar or 31.9psi.Secondly a 1.2 is really going to break up the clear to very fine droplets,so I would suggest you drop down to 28psi or less and see how that goes.Also the 4000rp only needs about 3-4 inches away from the surface,so if you are spraying at a greater distance you are wasting product,with that high of pressure you are wasting material by lots of excessive overspray.On a large car (like a 68-72 chevelle)I will use 1.6L sprayable clear per coat,so for 5 coats you might not be that far off.Why you are doing 5 coats is questionable :wak
The reason for 5 coats is that the colour was urithane kandy. Not your average collision work. The customer wanted the vehicle back earlier than planned so there was no time for sanding back, re masking, and flo coating.
So 5 coats was applied, 2 days later it was buffed and given back to the customer.
Also the difference between 2 coats and 5 coats of clear is unbelievable. So much more depth.I will drop the pressure down to 28psi and spray closer to the panel and i will see how that goes.
2 mils is the suggested amount of clear. For most professional painters that would be 2 coats. The most that i would apply is 3, any more than that you are asking for trouble. Too much film build is highly not recommended buy any paint manufacturer because of the chance of die back,chipping,peeling etc. :deadhorse
the founder of house of kolor jon kosmoski made a video a while back using his products, after 6 coats of kandy, 3 coats of clear was applied, sanded it all back and then applied 3 more coats of clear.
that dvd from jon is proof that you can do a paint job with 5+ coats of clear and not run into problems.
ive been doing just custom work for a while now and ive never ran into any problems like die back, chipping or peeling.
Well sure I can see that,but not 5 coats of clear all at once :rofl
does it actually matter if its applied all at once? i mean were talking about maximum build applied on the panel. it shouldn’t matter if its applied in stages or it one session. at the end of the day what ever way you apply it, the same 5-6 coats is on the panel.
I disagree,if you apply 2-3 coats let it sit for a day or 2 you will get rid of solvents and possible shrinkage.When you sand it flat that cuts out texture and gives you a smoother substrate for flow coating,so yes its different.I understand all about custom painting an how much material you can have,but you will cut down on problems with 2 clear coat applications.A video of someone endorsing his own custom painting techniques and product means nothing,lets see what the car looks like in person and after a couple of years.I have seen many a “showcar paintjob”that looks like butt due to too much material,sand scratch swelling,swirls etc.
Any RP I’ve ever sprayed has recommended 7-9 inches away or so with any 2000, 3000 or 4000 RP’s and the spray pressure is 29-35 PSI
As far as consumption reasons….the guns a pig…the clear is thin?
5 coats makes me nervous but that’s your call.

The new 4000 rp has a new limit of 2.2 bar or 32psi.http://www.sata.com/index.php?id=satajet4000brp&L=12(click on technical details) 7-9 inches away?Never heard or read that cant imagine spraying that far away and how long it would take :unsure:

Great post Jay. Another thing to mention is by putting 3 coats on, sanding and applying 2 more, not only will it be flatter then just hammering on 5 coats at once, it will also be thinner because you’ve sanded some mils away (at least 1 coat maybe more). IMO 5 coats of clear in one sitting is too much, It’s a dangerous game piling that many fresh solvents on top of each other.
I use to clear with my RP further from the panel, probably about the 8 or 9 inches and I can tell you that the positive results of holding the gun closer to the panel are real. You’ll use less product and get the job done quicker and probably with a better finish. For what it’s worth I get my best results at 27psi
