That’s the new thing in town, as it seems.
Nails Inc. is launching the first spray can nail polish. It makes application much easier and faster. All you have to do is apply a base coat, spray the Paint Can polish for about 20 seconds and finish with a top coat. When it is dried, simply wash your fingertips with warm water and soap or a face wipe to remove the polish from your fingers. It comes in two colors, pink and silver.
I found this site where you can see it in action and you can also pre-order it.
