Circles or Straight Lines?

Why not attribute your sources?

I am afraid to say that theory without actual check sometimes constitutes speculation.

I can see how this theory might be applicable only for hand applied LSPs where varying pressure from fingers in circular motion might result in uneven thickness of coat that would result in different light refraction. But back and forth will be uneven too.

But what happens with theory if wax is applied by machine, or even better if it is applied by hands but buffed by machine?

ZoranC - Try it and report your 'first hand' findings, then you would not have to rely on theory or 'speculation'.

Bunky - Perhaps you could try also as opposed to directing others
