Do Andrea paints ever go 'old' ? I have a few paints that have thickened in the bottle. Can I just add water (do I need distilled water?) to the bottle, shake, and I'm good to go?

Is the only thinner to be used with Andrea paints water?

Andrea has Field Grey which would work for German Grey uniforms, what colors would be suggested for the greenish-grey German uniforms I sometimes see?

FSM did a nice article awhile ago on Vallejo paints and uniform colors. The writer refered to Andrea in passing, but mainly gave the Vallejo paint numbers. Are there any good mixing charts or references specifically for Andrea paints for Uniform colors? For example- the FSM article mentions 'greenish -grey' as one color for a uniform. Andrea doesn't have a 'greenish-grey' , so, the question that come up is which green and which grey of Andrea paints to mix for this 'greenish-grey'.

Thanks for any info,

Peter

Nobody uses Andrea paint??

My Anrea paint hasn't aged yet, so I don't have any personal experience.
As far as I know, Andrea suggests water as the only thinner. It only needs to be clean tap water. Vallejo uses the same formula. See http://www.acrylicosvallejo.com/ " TARGET="_blank"> http://www.acrylicosvallejo.com/ for a lot of info on this paint.
