Crowning Glory vs Finishing Touch

I don't like Crowning Glory personally, if I had to choose only one prefer Finishing Touch. C&G leaves little dots on some flowers. Someone told me to use it on the back of Gerberas and stems or other flowers with large heads, it holds in the moisture better. I tried that with a few boutonieres and sprayed the front with Finishing Touch and they did hold up better, then the ones just sprayed in the front.

When do you recommend using Crowning Glory versus Finishing Touch? Do you spray individual stems, or the whole arrangement? Should the arrangement dry before putting in the cooler? ....loveblossoms
