This birch bowl (10" x 3 1/2") was rought turned a couple of years ago and abandoned. I pulled out of the burn pile and repaired a ring check with CA glue and finished turning it.
Wet sanded with walnut oil (80-320), applied Zinzers SealCoat sanding sealer (two coats with sanding in between), and the after resanding to 320, applied several coats of High Build Friction Polish.
