Dear everyone, Minnie tanks for all your feedbacks, I have given all the suggestions more or less a try, but on my bsa air gun stock first, which on balance is eve more horrible than the stalking rifles stocks. Not so expensive if I mess up

OK so far, I have given it a go with white spirit, unfortunately did not make an impression, ditto using WD40, washing in soapy hot water didn’t work either, however, the stuff the chaps who recently fitted PVCu windows and doors in the homestead left me to clean off any missed glue and mastic when they finished the job ( highly recommended firm, AEG windows Hampshire) definitely worked, see image. Only downside is, the fumes this stuff gives off would keep a gaggle of glue sniffing punks high for a week
