How does chrome perform as the reflective surface for a
solar parabolic collector. Is its effeciency comparable to
silvered glass? Are there issues with regards to weathering,
cleaning etc. Any links appreciated.

My first thought would be that chrome is very expensive and not done
much anymore as far as I can tell. You also know the "pitting" problems
with chrome if you have ever seen and old car bumper. I would think that
the reflectance would be good.
I think these guys use polished aluminum for their troughs, same principle
would apply to dishes, I would imagine.
Some folks use old C band diskes and cover them with relective mylar.
In this case, they used mirror pieces it looks like. Kind of extreme.

Chromium doesn't sound to good at 65%-70$ compared
to aluminum at 99% or so. See:
Yes, it is quite durable though.
Reflective Mylar "Greased" onto the surface seems a
better choice although it will be needing replacing
in a few years. The stuff is really cheap though. See:
