@pastryani I received the .5mm accessories and tried them out last weekend. Now, the only airbrush I've ever used is the Iwata, so that's my only frame of reference. But, spraying was SIGNIFICANTLY faster than with the default configuration (0.35mm). I think it took me between 1-2 minute per mold to backspray all cavities with white cocoa butter. I was pleased with the results and will likely stick with this airbrush until I open up my own business and production demands necessitate a more efficient airbrush.
Edit: Im not sure what model the compressor is since I'm not the owner (I'm apprenticing), but it looks like an ancient Jun Air.
