just a thought, never been washed, but no rust at near 5 years

As above, car does not get washed let alone waxed, cept for her first MOT Sept past.

When I pressure washed her myself.

Zero rust to be seen, i.e. when the dealership gave her a lick n promise recently, unlike some other threads on this forum.

So does washing n waxing only make owners Halos shine brighter, without any tangible physical benefits?
