thanks for the replies guys ? i'll go get some stripper tomorrow as it seems to be the way to go. (i realise that might sound a bit dodgy if not reading in context ???)
made a little bit of progress today:
pulled all of the frets and sanded the fingerboard
trial fitted a fret
(by the way chris, one of those retrotrons you gave me is hiding under that piece of newspaper ?)
here's the horrible paint situation :-\
