hi,
do valejo and gunze aqueous mix well?

I've never done but absolutely I don't think so

Gunze are alchool-based paints wheras Valejo are water based paints
If you try to dilute the valejo paints with alcohol, you'll obtain a sort of awful jam that you can't use it, so i think they aren't compatible at all

Tamya and Gunze are compatible and maybe (but I'm not sure about) Lifecolor and Valejo are compatible

Cheers

i said gunze aqueous not the mr color solvent range.

I've understood They are called aqueous but their thinner is isopropyl alcohol. In fact i usually dilute them with X20a tamiya thinner

Anyway you can try to mix them and paint a junk model or a plastic card piece

cheers

In a word, NO.

Just because it is an acrylic paint, doesn't mean they can be mixed with another acrylic paint.

Simple mechanics....Gunze acrylics are an isopropyl alcohol base, Vallejo is a water base.

And as Mauro has said, an alcohol base/thinner into Vallejo will gel it.

While you can thin both Vallejo and Gunze with water, you can't thin both with alcohol (or Tamiya thinner). Just simply a different base acrylic.
