Well directed silicone spray via tube supplied with can clears any grit and lubricates. Did this 3 times on last Crosstar over 4 years
In my book we shouldn't have to "hop through burning loops" to cover for a manufacturer's unwillingness to amend a design fault!
I'm quite aware that the "open to the elements" design of the mirror's mechanism is at fault and that applying silicone spray to the gear(?) might alleviate the problem.
However, I
do consider this to be Honda's responsibility to either:
* take care of during prescribed maintenance (which they - at least to my knowledge - don't)
* change the design of the mirrors (whatever happend to
"Kaizen" on this one?!?)
(they probably don't get Sahara dust in Japan)
