Hi, okay, so I finally got a decent airbrush set; well I decided against the Tamiya basic spray and got a better (more mainstream) set for a good price.
Haven’t gone into airbrushing my model just yet; needs a bit more practice of operating it (with plain water to simulate paint ;D).
Anyway, I also bought some paint from gunze’s mr. color range…I’m still abit new at this so I dunno if I did mix the paint quite correctly.
This is what I did: poured two parts thinner (also gunze’s mr. color range) and 3 parts paint. I used it on a small part of my model (handbrushing with Tamiya #00 size brush). The end result was nice and believable but after a few minutes, I noticed the paint in the cup has solidified or something like that; it looked fabric suspended above the thinner.
Is this normal for paints? I like the finish though. But it was a lot of work trying to clean-up; not to mention the intoxicating smell!
Have to confess that after seeing how the paint dry in the cup; I’m thinking twice now about putting it in my airbrush…
If you were to attempt to thin these paints with the alcohol based thinner intended for their acrylic range then it is conceivable that the paint will separate (the actual term is “flocculate”) in the manner you described.
On the other hand, I haven’t tried it myself but I understand that it is possible to use the lacquer based thinner to thin their acrylic paints.
Just to further clarify, Gunze make two ranges of paint. One range is acrylic based (labelled “Aqueous Hobby Color” or “Mr Hobby” in some markets) and the other lacquer based (labelled “Mr Color”). The acrylic thinner cannot be used with the lacquers, but I believe the lacquer thinner can be used with the acrylics.
