After hoarding supplies for a long time I am trying to thin out my stash. I have 2 types of Vallejo air thinner, for argument sake the old milky one and the new clear one . Obviously the new one came out due to short comings in the old milky one. Which is actually best? Also I have stumbled on Vallejo 919 foundation white does this stuff actually have a good use. I have always preferred a solvent based aerosol primer (Tamiya)

Thanks

Use the old (milky) for thinning standard acrylics....and the new (clear) for airbrushing......
Foundation white has more pigment for added opaqueness....not ideal for airbrushing (requires more thinner).
