ExpandI still don't know how to get full coverage without multiple passes
Even when flowing freely, the spray pattern is only half to 3/4 an inch wide. I personally don't worry about getting good coverage all the way to the edge of the cavity, but you can try the fan spray cap for a wider pattern. Coincidentally, I just noticed this store is having an anniversary sale, 15% off online today (3/29) through Monday with discount code 21ANNV
I like Roxy & Rich colors and mostly use their sparkly 'jewel' line. Available from chocolat-chocolat or I think Tomric is carrying them now and also webstaurant store. I'd gotten some samples of their natural line, need to test those out and report back because more states are banning more food dyes. West Virginia just banned a bunch, don't think I've ever sent chocolate there but this could be a trend.
