I have seen reference on the list to the fact that
some of the newer (non vintage) coaches do not lend themselves to polishing the
exterior skin because a different aluminum was used compared to earlier
trailers. When (which year) did the new skin material change to the "non-polish"
type?
It presumably would be easier to fix minor
scratches and scrapes from normal travel and use if the skin can be polished to
remove minor surface blemishes. Thanks.
