I use the spinner for aerosol cans of paint. Love it.
For small bottles, such as craft paints, I use Painter's Tape, wrapped around my handheld Jig Saw's blade and the paint bottles. It has a variable speed trigger. It shakes the Devil out of them, quickly, efficiently, without killing my arm in the process. I love it.
The Painter's Tape can be used several times before I need to peel it off, and replace it. Cheers!
