Thanks for your reply, throbgod (great name!) I've actually only beeswaxed the wenge neck fretless once & never the ovangkol's fretboard so should be ok but as I'm an unco with woodworking, I'd definitely leave all the great advice you gave to someone without 10 left carpentry thumbs, hell, even opposable thumbs would work, which is basically where my handicraft skills lie. Oddly, I'm good with setting up my own basses though??!! Go figure!? Thanks again.
