It penetrates into the cells of the wood to restore its holding power. It contains no oil...will not evaporate.
Its effectiveness improves with age...in one week the pins are tight enough to permit tuning. It prevents rust...will not affect glue.
4 oz bottle.
Must be diluted with equal amounts of denatured alcohol.
