That isn’t an argument, it’s a schism.

Sheldon says grease, though. A little bit.

I will add my own discovery in the field and that is that the super slippy Teflon grease that comes in a little syringe is not good.

After washing the tapers with acetone and using a smidgen of copper paste instead (which has a kind of a greasy base, but not super slippy greasy) they seem happy.
