Sometimes I use WD40. Is kerosense any better than WD40 or the effect is similar?

TapMagic is great on Aluminium. WD40 also have a dedicated fluid for machining in addition to their traditional (W)ater (D)ispersant 40.

Would stay away from WD40 for anything with enough cutting-force to create smoke...

When I started out I used it and fairly frequently I would get these crazy heart-palpitations with my heart beating at a mile-a-minute and so hard I could properly feel it when I put my hand on my chest, stopped using WD40 and it went completely away...............

So it would appear that once you heat WD40 past it's smoke-point some kind of CNS active compound is created............
