15” AFS
If you are in the collision repair industry this will probably be your sander of choice, in fact it may be more sander then you need. It'll easily allow you to find the lows and restore the panel to better then factory condition. This is also a wonderful tool to have in your arsenal when you get into tight spots with the 21 and need a little more swinging room.
