I was frustrated with Vallejo paints. They dry in the airbrush tip This stuff does help reduce the annoying drying and makes the whole process easier. Enamels spray nice, but are a mess to clean up. I love the water cleanup with Vallejo and this product has helped me transition to water based paint.

I have some Vallejo Model Color paint that I use this for, it seems to work with Tamiya as well. Just added a couple of drops to my airbrush and paint and didn’t have a problem.

Great stuff, note the label design on mine was a little different than the images shown here, but same product.
