Hi again. I just want to make an update.
Recently i had gotten a bottle of mpg, mobo propylene glycol, which is industrial glycerine, mainly used for vaporizers and such. Well, that was the missing ingredient i say. I added around 7 8 percent to my thinner mixture, and both MC and ma series are easily airbrushed under 20 psi with less dry tip. Whats surprising is, it dries within 4 5 seconds after sprayed, so dont be afraid of the amount of mpg ratio, it gives a great fluidity and consistency to the paint Flow.
Cheers
Baran
