I am wanting to know if anyone has any suggestions as to how i can spray ppg concept dcu 2055 with out getting orange peel(or any clear for that matter). I have tried everyhting and am using a sata rp at 29-35 psi with wide fan and moderate amount of materials. I have adjusted this gun every which way and can not get it to lay down clear. Ready to go back to my devillis "war heroes" at least they work.

Ya got to pour it on with HVLP.
Spray it how ya want it to look!

Follow these instruction and you will soon be laying material wet and slick..

Thank you sam, I will try this. And for the other guy; I am sorry but a rp is not hvlp, thanks any way.

Dave,
Any time you buy a new gun you will need to go through the adjustment drill..One trick is to run about 100 psi at the wall and then adjust the air so you get about 25-35 psi at the cap and those guns like that a bit better, You may need to tweak it a bit to get the atomization right..then starting from completely closed open the fluid until the gun starts shooting and try that on a test panel..Then keep tweaking until you get there..once you have down then make a note of the settings for that gun so you can back to the right settings when you take the gun apart for cleaning..

are you using reducer, how much, what temperature, what size tip is it?

[David buell]

Yes, MitMaks I am using reducer. Always in accordance with weather temp. Since every car I do is a overall, I usually use high temp so i can "try" to get it to flow. I mix first coat according to directions, and add About 10-15 % more reducer on second coat. When using ppg dcu concept 2021 or 2055 it does not matter what or how i do it, it looks like rocker gaurd. Have accused my supplier of buying seconds, he did not like that. Have even showed him what i ca do with other clears such as Nason. I can lay down Nason 496-00 like glass, just wish it ways higher end like the dcu concept is supposed to be. If you can shoot me good advice like Sam has, have at it.

[mitmaks]

Im thinking this clear has more solids unlike Nason thus it needs more reducer. I personally always overreduce paint/clear to lay it out with HVLP, bumping up pressure helps out too.

I use 2020 clear, but the same process.
As well as with the DCC solid colors.
I've found that with the HVLP, you want to over thin just a tad.
Use the proper cat. and reducer for the conditions.
Turn the flow down just a touch, and shine it as it goes on.
IOW, spray it wet. What it looks like when it hits the surface is what it will look like after it dries. With the SATA, I,d crank up the air just a little as well,
They don't bust up the paint as well as they should at lower pressure.

I couldn't have said it better. Follow those simple directions and you will have a nice bc/cc paint job that will not require any wetsanding/buffing unless you got dirt in it.

Wow, I asked for advice and got it. I am going to spend plenty of time spraying test panels before spraying my current job. Thank you everyone for all of the advice. I will post again when I get results. Any other suggestions are welcome.

[David buell]

Thank you for all the help, clear coat is almost like glass. Turned up inlet psi, reduced material flow. Are there any better guns than sata, or how do they compare to the Iwata. What is a good gun, my partner is looking for one too?

just remember orange peel is almost always too much material . urethanes don't flow . shoot for effect . sounds like you got a handle on it.

I prefer an Accuspray, with a 1.6 fluid tip, and a #7 air nozzel.
