Phil Payne,
Yup, its the real thing alright! and you can lick your fingers after
you've finished.
IMHO, WD40 is not the pre-eminent looser of rusty nuts though
(steady....). Although WD40 is a magic lotion for many applications I
know there are several products available in the States that are made
strictly for rusty nuts.
