I have a quick question for my ref. What do you call Turps down under if turps is white spirit down there? I ask as white spirit and turps and two completly differant products here, we thin with white spirit and clean gloss paint off of brushes with turps as it is so harsh.
Hey Darren,
After a little further research, it seems my earlier post may have been in error.
It does indeed appear that White Spirits (in the UK), White Spirits (in Australia) and Mineral Spirits (in the Unites States) are the same thing (namely Stoddard Solvent)
and
Mineral Turpentine (Australia), = "Turpentine Substitute" (eg. Turpenoid in the US) = Mineral Turpentine (UK )

why do they have two types of acrylics? 
talk about complicating manners I purchased mr. color # red and mr color light blue # 323, one has flat cap and other has paddle cap you sure generic laquer will work to thin mr color? mr color thinner is $13.50 for a small container....very expensive.
Dave,
I suspect your red is an aqueous acrylic and the blue, according to the number is certainly a lacquer based version.
To be honest, I haven't used Mr Color lacquers yet (they're difficult to come by here in Australia) so it's really just a guess/assumption that generic lacquer thinners should work. Having said that, lacquer thinners can vary in composition between different brands. Personally, given a choice, I would go for the Mr Color thinner because it eliminates any doubt and t is styrene friendly and won't melt your model as generic lacquer thinners may do..
Look at the larger size bottles of Mr Color thinner, as the pricing isn't proportional to the quantity and the large sizes are progressively cheaper It is expensive compared to a generic thinner, but when that expense is spread over a number of models, you're not really spending much more than a dollar or so on thinner per model.
Come on, you've already spent maybe $40.00-$50.00 on a model plus accessories etc, why skimp on paint /thinner and risk a second-rate paint job?

I am going to try 50/50 with Tamiya acryl maybe with some acryl retardent, that may explain why I have such a grainular finish on my planes,just dries too fast .I flush out my airbrush with hot water right from the faucet and back flush ect at 40 psi, maybe unusual? but works everytime to keep my Paasche millenium running smooth..at leaat with acryl paint.
Your Tamiya thinner will be fine with the aqueous acrylic but it won't mix at all with the Mr Color lacquer. I use Tamiya and Gunze Aqueous acrylics almost exclusively and usually flush/backflush my airbrush with denatured alcohol. I'd suggest not putting tapwater through your airbrush to avoid possible mineral deposits over time. If using water, use distilled or demineralised water.. :
