Thinning Floquil in 2020

[Sharky_McSharknose]

The model rail group I am a member of has some jars of Floquil paint left. I am working on a building for the N scale layout (this one: https://www.walthers.com/hudson-ice-coal-co-9-1-2-x-4-x-5-quot-23-7-x-10-x-12-5-cm) and want to use the Aged Concrete paint for parts of the building. I will need to thin it and there isn't any Floquil thinner.

I have mineral spirits, acetone, and 91% alcohol on hand. Of those, would you use any for thinning Floquil paint for airbrushing?

If you are thinning it for airbrushing I would not use any of the solvents you mentioned - use generic lacquer thinner instead.  But just thin as much as you'll use during that painting session (because it messes up the paint's chemical balance). But for immediate use it will work well.

For some more details on the original and Rev I DioSol see this post and the rest of the thread.

Thanks. I borrowed some Tamiya lacquer thinner to go with the Floquil paint. I don't think I'll need much of either so I'll mix them in the airbrush cup. There's just enough of the Floquil that hasn't turned into mush that I can still use it.
