Finishing all sides of small parts is a lot easier if you don’t have to hold them by hand. Here’s a little helper I use: I attached a suction cup to the end of a large dowel that’s long enough to serve as a handle.
After you’ve applied finish to one part face and the finish cures, the suction cup will stick to that surface. Now you can finish the rest of the surfaces of the workpiece without getting finish on your fingers — or fingerprints in the finish! Works great.
