I have built a few models in the past using a brush with Tamiya paints and thinning them with isopropyl alcohol. I am currently building a StuG IV and it will be my first attempt at airbrushing a model.
I need to run to the store to grab some paint for my latest project and got to thinking that I had seen Tamiya acrylic thinner advertised before. My question is, when airbrushing is it best to use the Tamiya thinner, or will isopropyl alcohol work too? I also have access to RO water if that will work as well. I don’t mind buying the thinner but don’t want to spend money on something that isn’t necessary
