hey guys!
i have a huge problem with my guitars neck! it's strarted to get really dirty and the contitioner doesn't response!

fook!
i found out this prouduct :
http://www.nanophos.com/en/SurfaPoreW_en.html
(Water repellent for protecting wooden surfaces)
that's nano tech for woods (makes the wood dry)
and finally put
tung oil to protect the
maple neck!
does it work??? or only the nanothing?
also....does the tung oil works on fretboard????
anyone?
