Watching a turning demo at Rockler the demonstrator mentioned spraying water into his turning (bowl) before the final finish cut. He also suggested wet sanding with walnut oil to fill small tear outs.
Along these lines it occurred to me to use a heavy coat of quick drying sanding sealer to more or less stabilize the wood from small tear outs or rough spots especially where you might be working against the grain.
Any thoughts on this? Anyone tried this?
