I have a question I started airbrushing about a week ago trying to do lexan RC car bodies. I was using Testor "Pactra" Racing Finish. It's a lacquer paint and after reducing sprayed wonderfully, great control no clogging issues just very potent aroma.
So in order to practice technique I thought it wise to use some paint that was a lot less toxic. I went to my local arts and crafts store and picked up a 6 pack of the spectra tex opaque and some of their brand cleaner. I printed out a bunch of the practice PDFs from the website and eagerly set up.
Now with this new spectra-tex I am having horrible flow issues. It will not keep a steady spray of paint. I tried it straight out of the bottle and different ratios reduced. I could not practice at all today as I was trying to solve this problem. I have 3 brushes, all had the same issues, when I tried using the other paint "pactra" it was smooth again.
Any ideas would help a lot I would really like to get to painting.
Heres what I was using.
iwata eclipse HP BPS .5 needle (3 different brushes same prob, took apart and cleaned)
psi I tried several ranging 15-80
spectra-tex opaque black (reduced and straight from the bottle)
i can't think of any other variables, I read about pulsing and checked seals, needles, and it didn't make sense to me that one paint works and the other does not.
sorry Im reposting this in troubleshooting. Didn't mean to high jack this. Admin feel free to delete.
if i had to choos only one system to go with spectra would probly be the top few to decide from the white especialy does well with the infinity
they should be no reason on earth why spectra should not go through a .5 nozzle, I mean, as ferret said he can put it through his infinity which is a .15......on comparison yours is like a fire mans hose.....only thing I can think of is to thoroughly shake the paint, has spectra got the little ball bearing in like wicked has, to mix the paint? if not maybe consider getting one if the little battery operated paint mixers? if the paint is new there should be no clots in it but you could try straining ir through a pair of tights/pantyhose
Resurrecting and old post here but doing so requires less explanation.

Its not lightfast, will fade over time.

i believe imaginaire has the only true waterbased candy range for airbrushers, AA is pigment based and not a truenone but imaginaire is. But its a bit pricey though. (In europe atleast)
I just looked it up Rick and it does look like it needs to be imported, I will have to look around at what other water based paints for plastic there are that is lightfast and wont fade.
Wicked, auto air, schmincke, etac, comart, golden, hansa procolor, vallejo, trident, molotow and a heap more.
Great, I will check out the specs for each one.
