I'm in love with this new Fuji spray gun! For the first time airbrushing I finished without coloured hair or blowing blue snot. Minimal aerosol, and can be made less by turning down the volume of air.
I made up chocolate with 30% extra cocoa butter, then used it to spray a frozen boot. I screwed up a bit - the chocolate was supposed to be 50º C when I sprayed it - but it was around 30º. I think the suede look would have been better with the temperature right. And of course it doesn't help that I've now got finger prints on it.
I then took the same mixture, turned the air pressure right down until the chocolate sputtered out of the needle - perfect splatter! It was a simple matter to dump out what was left in the container - wipe with a paper towel - heat with the heat gun - wipe once more - then blow the air through until no more colour came out of the needle. Then I added a coloured cocoa butter and sprayed.
This gun will not allow you to do a thin line (but I don't think any spray gun or airbrush will). The unit we got is the Q4 turbine - Q for quiet - it still makes a fair amount of noise, but it's not at the ear splitting frequencies of my compressor, so it's a whole lot easier to tolerate. I think the extra $200 for the quieter turbine is money well spent. I'm going to keep the 6 foot flexible hose and the attachment with the air control valve in my stuff - and let hubby get another one - because it was covered in coloured cocoa butter fingerprints when I was done. This way I don't have to worry about food safety issues because we are sharing the turbine.
By the way, I emailed Paul from FujiSpray, and asked if it might be possible to use a plastic sack, e.g. made from a ZipLock bag, in the non-gravity feed pressure pot. He says that some people do use a plastic bag for spraying paint.
I don't think there are any food-safe issues to deal with but using a sack may provide a very fast way to switch colors.
