Two ideas come to mind for a finish. Brush on some cheap "poly-something-or-other" from the DIY store. Or a can of some cheerfully coloured spray from the same place or a car accessories place. Any opinions?
If the uke isn't so nasty that it would put someone off for life, I might get a few more as kiddies presents.
