Thinning Model Master Acrylics with (filtered) water?

I'll start by saying that I don't use MM acrylics, nor do I thin acrylics with water, but I would be hesitant to use tapwater, filtered or otherwise to thin acrylic paints. A domestic filter will only remove particulates from the water, but it may not remove dissolved minerals.

If you do use water, I'd suggest demineralised or distilled water, which can be found at auto parts stores or perhaps even your local grocery store.

I hadn't considered the minerals. Luckily, demineralized and distilled water are easily obtainable and much cheaper than Testors thinner. Thanks for the tip!

I have thinned MM Acrylics with distilled water, denatured alcohol, Testors, and Tamiya thinners. all will give good results. But I have never tried straight without thinning... too thick to my eye. Thinners give the best results then waterm and finaly alcohol as far as cloggin due to drying in the aribrush goes in my experience.

I have an excuse to pick up some distilled/demineralized water tomorrow, so will do just that. If I manage to get going early enough, I'll be able to do some test shots, as well.

Edit: I brushed some Model Master acrylic (Interior Green) on my P-51D project a bit ago. It brushes on decently, so I think Tower Hobbies' claim that it can be airbrushed without thinning is a mite exaggerated.
