Regarding JB bore paste, I seldom use it but my old jar is dry grit now. Can you add any type of oil and stir it back to being usable?
Add a drop of vegetable oil and work that in. Add as needed but go slowly.
Or a few seconds in the microwave......
Microwaves work with many things. One of my best friends is really into "affordable" stuff, even though he's done very well in his career and retirement investments. But one of the things he did for many years (and may still) is put the last little fragments of shower soap into a small glass bowl, and micro-wave them until they form another bar.
Am sure this saves him at least a dollar every few months.... Meanwhile, his investments have allowed him to go on quite a few trips from northern North America to Africa....
