first of all, it cant rust since its not metal, and second, yes, you can
remove it and just leave the groove open. it prys right out.  i have done
it
with 3 vanagons, with no leaks.
it looks better than that nasty faded out fake chrome plastic trim..

I think there may be something new under the sun!  I've been wondering the
same thing about that trim, because it is in fact rusting.  There appears
to be a thin band of metal under a plastic laminate.  Starting from the
clip location, the rust is spreading evenly in both directions and is most
severe at the clip.  My guess is that origionally the metal and platic were
somehow bonded together and have now seperated allowing the water in.  What
are these trim strips made of in your experience and why remove them if
they are not rusting?
