Good advice Muskett. Its good to declutter as well one doesn't want one's relatives to chuck it all in a skip once you've moved on.
Someone bought my battered original can of Dri-Slide from 1981, which was still a quarter full. I got it by post from Eddie Barber's Airgunaid shop. I think I got a fiver for it.
I could have held onto it for sentimental reasons, and also for tuning springers, but it was a messy thing and so I thought f-it and off it went to someone who would love it properly.
I just get dry moly powder and a pinch of moly grease or a drop of gear oil and mix them into a paste if I feel the need for moly coating something.
