Fingers and nails protection

When I use my flex shaft machine, whether for polishing or with
burs, I invariably miss or slip, and hit my fingers or nails. Swest
sold 3M Coban Self-Adhering Wrap (they sell the same thing at the
drug store now, as an alternative to Ace bandages) which I use to
wrap my finger tips when I’m going to be using my flex shaft. Is
this a bad idea? What about if I’m using a bench top buffing
machine?

I appreciate any thoughts or observations anyone might have about
this.

Thanks.
