I have read about using Liquitex flow aid and reducer to improve the spray properties of acrylic paint. What are your experiences and mixing ratios? Anything to watch out for?

Thanks

Don't know what brand of acrylics you are using but I have been airbrushing Tamiya "acrylics" for many years without the use of a flow aid or retarder. I do thin the paint with their yellow cap lacquer thinner and get very good results. Mixing ratios vary depending on a number of variables including local temperature and humidity and how you prefer to paint. I like to build my paint slowly using very thin coats so I tend to use a higher thinner to paint ratio and spray at relatively low pressure, but a good place to start with the Tamiya is 1:1. Hope this helps. I'm sure others will chime in. Good luck.
