ULTIMATE AIRBRUSH THINNER, for the last time. Can be used with a broad variety of paint.
I’ve always used nothing but traditional enamels, particularly Humbrol. I typically thin mine with a 50-50 mix of hardware store lacquer thinner and mineral spirits, 50% thinner to 50% paint, spraying at a relatively low pressure (12-15 psi), adjusting as necessary to get good results. Proprietary thinners are best, but they can’t always be found when you need them, and per unit volume are horrendously expensive compared to generic paint thinners. Plus, I’ve never experienced a significant difference when using generic thinners.
So-called “acrylics” are a different story. They all seem to require the manufacturer’s own thinner plus flow enhancers and other additives to get them to work properly, and at my age I don’t have time to play paint chemist in order to finish a model. The exception are Tamiya’s “acrylics”, which actually are alcohol-based enamels. I’ve not used them often, but when I have, I’ve found them very easy to use and yielding consistent results when used with their own thinner. Their only disadvantage is that their range of colors is more general and does not include most of the specific camouflage colors we need.
Welcome to the exciting world of airbrushing!
