if it does'nt adhere to the model I don't care what it looks like. Acrylics are a wonderful medium in which to work,that said they also seem to be the toughest to use as each brand seems to have its own quirks. I have sprayed Tamiya bottle acrylics thinned with tamiya thinner and gotten perfect results. Water will slow down the drying process which has a tendency to produce runs and poor adhesion to high spots, while using alcohol works just the opposite, causing uneven color on uneven surfaces. The tamiya thinner which I think is high priced, does seem to work the best every time for airbrushing......for hand brushing take your choice!!! they all seem to work there
