Adjust for more air pressure.
what doesn't sound like enough air, 34-35psi? depending on what gun, The devilbis plus runs at 28-30 and my Sata ran at 27-29. I think some of the Iwata's are run at 20 or a little less. The days of the 40+ psi are long gone.

I would have to disagree. My Sharpe 998 I have the same problems and same reactions when sprayed at lower than 40 psi. Spraying at 50 psi I get a smooth job every time.

Is that the siphon feed? If it is, thats why. That and it's a SHARPE . Siphons tend to take more air. And I've always tended to have to run higher pressure with my Sharpes. I have the Titanium. And matter of fact I think I have a 998 that I got back in 1997. If that is the same gun, that is ANOTHER reason. HLVP technology has come ALONG way since then. Look it up. 98% gravity feed HLVPs take less than 40 psi. And your HIGHER quality take less than 30.

The SATA 3000RP and HLVP are 29 psi while there siphon feed guns are 36 psi. The Iwata lph400-lv and lvx are 16 psi and their lph400-lvb is 14! But their siphon pressure cup lph200p and lvp are 28 psi. Your cheaper guns like Harbor Freight HVLP gun take WAY more air. It all depends on the quality and efficiency of the gun. Higher psi causes more overspray, thus a less efficient gun.

Yes it is the siphon feed. I am an old dog, I started painting with conventional guns and that is why when I bought it I went for the siphon feed, have never cared for the gravity feed.

The results seem to be consistent with not enough air pressure making balls with the paint not atomizing enough and he said it looked rough but was not to the touch, if it was dry spray he would feel it rough

Right. I re-read his posts and it is his GUN. It's a HF gun and THEY have to be shot at higher psi. See my edited post before this one. So you are right, he needs to bump the air on THAT gun, but like I said, ALL high quality guns shoot at lower pressures.

For some reason i stopped recieving emails for this thread i made... thought nobody was responding...


This is the car i just sprayed the other day with the HF purple gun... 35 psi. dupont chromasystem bc and dupont nason 497-00 overall clear.

---- I actually had a potential customer want me to paint his car, and he told me he has "hook ups" with Sata. He can basically get me any gun i want. In order to help pay for the paint job...

So... I was thinking about the satajet 3000b... He said he also could get debviles... so he told me to give him a parts list, and he will see what he can do.

What guns would you guys suggest? (these would be used for bc/cc)
Or if its a cheaper gun i can get 2 and use 1 for bc and 1 for cc.

I personally would go with a Devilbis. I would put the Devilbis Plus up against a Sata 3000 ANY day. AND this is coming from a die-hard Sata fan! They are almost half the price. So you could get 2 or just get one and put more money in your pocket That Devilbis will be MY next gun.

I don't have a dog in this fight beacuse all I have used is Sata since going HVLP. I did a bad thing and got a Sata 3000RP digital and love the finish I get from it but it isn't HVLP. The 496-00 is a quick drying clear and only suited for panel repairs, at least in my opinion. The last time I used it was on some parts for a bullet bike and it was dry way too quick for my taste. I was spraying at 39 psi from my 3000RP to get a nice finish and that resulted in a big ole cloud in the booth. I've stepped up to Southern Polyurethane universal clear and won't use any other clear now.

Why is that a bad thing. The only thing I can see you did "bad" was spending the extra money on a digital instead of a non-digital. I have heard and seen lots of the digitals turn black and stop working. To me the digital guage isn't worth the added expense. Besides the RP will give you a slicker finish FASTER than a HVLP. AND it doesn't use anymore paint.

--- I didn't use 496, i used 497. 496 is a panel/spot repair clear, and 497 is a overall, large panel repair clear.

As for a gun for me... I am still new to this painting game, and haven't used any high quality gun yet. It's all whatever is available to the customer who has a sata connection.

A buddy of mine who is a paint tech for a chemical company swears by the GFG+. He does lots of restorations and general paint work in the evenings and swears he doesn't have to cut and rub any of it.

I was referring to the red Honda. The black VW(?) looks like you're getting a good handle on it.

That's the one I use and will guarantee it sprays as good as any SATA. AND at half the price.
