I like bitsas. It's always fascinating seeing the ideas other people come up with that you would have never likely thought up on your own.
As for WD-40, I gained new found respect when I used it on my completely seized height adjustment pivot points on an early 80s utility that had been sitting partially exposed to the weather for four years+. Didn't do anything st first, but to my surprise, it moved up and down freely when I tried it after a week has passed
