  1. I've also had issues with 3rd. gen acrylics when it came to airbrushing. I have tried everything from black (always easier to airbrush darker colors due to pigment size) to white and fluorescent orange (larger pigment size, harder to spray). These have gone through my sparmax sp-35x (0.35 mm.) and my Mr. Procon Boy FWA Platinum (0.2 mm.). Tried varying thinning ratios and air pressures. I initially had the same results as here, sputtering, clogging and having to deep clean the airbrushes (spent several hours cleaning threads on the nozzle of my Procon Boy). When using optivisors I realized that I had thread-like bits of paints when mixxed with the thinner. I always mix outside the airbrush cup, so these were easy to spot. For all other paints (vallejo, tamiya, gunze, alclad etc) I usually stir with the tamiya metal stirring rod or something similar. What enabled me to spray these AK 3rd. gen paints was to mix the paint witth the 3rd. gen thinner in a cup using a brush rather than a stick. Stirring with a brush really well and using more thinner that I thought was needed, solved the issues of airbrushing this paint. Aditionally (and this goes for every paint brand), paints will have to be thinned to different ratios based on color, although some are more forgiving. In AK's case with the 3rd. gen paints, stirring and mixing properly with a brush is absolitely vital I have found. On the note of Real Color, these are easy as hell to work with. Just mix with MLT and spray away. I have found their dunkelgrau to be too dark (shoudln't these account for SMF?) but other than that they work well. In summary for the 3rd. gens: Thin generously outside airbrush cup Mix very well with a brush. My local hobby store worker told me that their 3rd. gen thinner is made in conjunction with the paints, hence it's supposed to be superior in that regard. Don't know if that is for selling more thinner, but it's perhaps worth a thought. It smells like alcohol, same as the ammo thinner, so I believe the alcohol-components make the paints need to be stirred very well. Vallejo's thinner smells differently and seems to be more compatible with most vinyl acrylic paints, moreso than AK and AMMO.
