When sanding elevators on a flat surface (such as glass), I found it very hard to hold the small parts steady. Taping a sheet of fine sanding paper (rough side up) proved to be a lifesaver for pieces not slipping & sliding all over! Just use a regular sanding bar to sand.

I thought I would pass the info for the newbies

Newbies are not the only ones who can benefit when someone shares their experience.
