Silver NOT!!  And here is why.  A couple of years ago I was talking to the
guy at the local body shop about painting the top of the pop top white or
silver.  It was a warm, sunny day. He took me over to some vehicles that
were parked outside the shop.  One was white and another silver.  Then he
told me to put my hand on each.  The white car was a little warm but the
silver one was to hot to keep my hand on!!  He explained that the only
silver colored paint that was avaialble and would hold up on a vehicle gets
the silver from the metal flake in it.  And that it doesn't reflect the heat
from the Sun.  But that most whites or shades thereof did a good job of
reflecting sunlight.
So, there may be a silver reflective coating out there that would work but
not in a body paint.
