I know this is a long time after the original post, so maybe the company has made changes by now?
I just used his silver spray for the first time, my airbrusher decided to quit on me the morning of a wedding, so it was an emergency quick fix.
It did smell nasty, like regular spray paint, but that didn't last long. I was covering white fondant, both smooth and figures, it covered beautifully, didn't drip or pool, dried quite quickly and had no taste.
Maybe I got really lucky, or they fixed the old problems. Either way, I used 4 cans and they worked perfectly.
Finally a product of his I like! lol
