ANYONE please correct me if I'm wrong. But the characteristic shared by all acrylics is that they cure as a film, and water based ones like Vallejo don't adhere to plastic as well as a solvent based paint will. This does make masking Vallejo tricky, and makes things like masking fluid work not well, as it will continue to peel up past where you've masked.  Where as a chipping fluid from Mig or Vallejo requires saturating the acrylic top layer with water to cause a reaction to the fluid underneath and makes a controlled peel lol.

That being said, to my knowledge, the only lacquer thinner that should be used with Tamiya Acrylics is Tamiya Lacquer Thinner (Pale yellow cap) as that causes a specific reaction with the Tamiya acrylics solvent, and actually turns the paint into a lacquer. I've been told by my LHS owner that using Tamiya Lacquer Thinner with Mr. Color lacquers works fine, but the paint may not be shelf stable.

I have thinned Tamiya acrylics with distilled water and 91% rubbing alcohol with good success as an FYI as well.
