Thank you! I always get the powder stuff. Never used the spray before. But if your doing a lot of painting, maybe the spray would be easier/faster. Depending on the paint, it will normally dry pretty quickly (couple of minutes) then I use the power. I have also had times when I was face paining, but getting a little sweaty (which makes it hard to get the paint smooth out), so I use the powder to dry it up and seal, and then layer another coat, then powder again.
