If you direct the application to ONLY the threads, you wouldn't see much change. Our lug nuts are tapered. The reason they are tapered is to increase the surface area between the lug nut and the wheel to prevent loosening. .
If you keep the AS off of the countersunk area, there shouldn't be much difference in torque being delivered and how well the nut stays tight. Some, but not much since the countersink friction is what determines most of it.
What I was taught, funny enough, first by my High School shop teacher, 1987 or 88, can’t recall. Not sure that descriptive, but same message.
I hear him saying less is more, threads only.
Pretty amazing how much that teacher taught…more amazing that we paid attention. He was a good guy.
