I was wondering about the spray color in the can they sell at the craft store in the cake section.
I am doing a grooms cake and I wanted to find out if it was really worth buying.
Anyone with experience, please help me out with advice.

I'm not a fan. It works in a pinch since I don't have an airbrush, but I don't find it covers well. It has a tendency to sputter and leave blotches.

My aim was a light spray of yellow, and it blotched. I used it on a few other cakes where I wanted sky and it did the same.

I have an airbrush now but before I would use them abit.They are okay for a quick spray.

I too have used it on the golf cake in my photos. I wanted the cake sides white and the top green, so I iced the whole cake in white and sprayed the green on the top only - or so I thought. I found the spray was hard to get good, even coverage (but that may have been because I wanted such a dark colour out of it) and it did pool in some areas. Also, as you can see in the pic, it started to run down the sides (I sprayed it on before I did the border as I didn't want spray on the border). I found it hard to control where I wanted it to go. Perhaps the worst part was that I was wiping green off my kitchen counter for months (seriously, months!), so I learned that if I use the spray again, cover the counter first.

I have used it on my kids birthday cakes before. To me it added undesirable flavor...kind of mint like. I also found the coverage to not be that great like some of the others stated.

My main problem was the weird flavor it added.

I've used it too. And as the others stated it was hard to get good, even, coverage. There is a cake in my gallery, black with a red design, that I used it on. You can see on the black coloring how it is kind of "smoky". I have used it for stenciled words that I wanted to look soft and it turned out ok for that.

The Wilton edible colored sprays are give good coverage but taste HORRIBLE!

Run far away! Not only did I have problems with evenness and blotchiness, my whole kitchen was covered in it by the time I was done! The overspray is ridiculous! And it did taste horrible.

Ugh. It is horrible. A couple of weeks ago I needed black fondant for a last minute order, and my local supplier didn't have it. So I bought some of this stuff. It is complete and utter crap.

if you don't have an airbrush this is a very economical solution.

I am not very pleased with the selection of colors though.

Like every one has stated there are problems with it. Be sure you lay news paper under and around your cake. I did mine outside on the patio table covered with trash bags and I had no overspray problems.

If you want a dark application then I would allow time for a ligh spray and a 2nd or 3rd coat, just like you would use spray paint.

also like spray paint you have to start the spray off the cake and then sweep it over and keep the can at least 12 inches away.

I was looking into an airbrush, I think that's the best way to go.

I don't mine it! I have used them a number of times.
Some of the sprays have flavour added and it is gross but... they do come flavour free and I think it works well. (make sure you read the print on the can to see if there is flavour added)
It is like a can of spray paint you need to have a light hand and a a few passes.
Over all if you do not have an air gun it works great!

I used the black on the Batman cake in my pics. It worked fine for me, I needed the blotchy dark sky look (which turned out greyish/brown). . . . . I didn't notice a bad flavor but it is not for even coverage!!!

Ohmygosh! YES! I forgot about the overspray!!! My counters were green for months! And my white linoleum floor 20 ft away ( i was spraying in the opposite direction) was green.
