I use the same thinner for Model Air, and Model Color, Panzer Aces,,,,,,,I also use it in their Game Color paints, but, those are soooo thick that I use a lot more of it when using Tinny Tin, etc,,,,,,,since I use 4 different ranges of Vallejo paint, with the same thinner,,,,,,,,the ratio varies all over the place
they have their own thinner,,,,,,I use that, along with a drop or two of Flow Medium
the bottle number I have is #061, it is 32 Mil (about 1 ounce),,,,,and has additional binders so that the thinned paint won't get diluted, just made thinner,,,,,,,,,,,,it looks like extremely thin white glue when you drop it out of the bottle, don't worry, that is the normal look for this stuff
