Having taken advice from some of the posters here, I had my E30 318is
resprayed in 2 pac.  It looks 'as new', and I'm very pleased with the
paintwork.  However, there is now a rattle that is driving me sparse.

Behind the drivers side back window is a curved piece of metal that tapers
from around 5cm wide at the bottom to a point at the top.  It looks like an
extension to the outside of the roof gutter.  The spray painter told me that
there were some clips on it that plugged into some oval shaped holes in the
body, and that they wore a bit when removed and replaced.  I've noticed that
if the bottom of the fitting moves out from the body then the rattle is bad.
If I push it back towards the body, the rattle stops.  For a while.  I took
it back to the spray painter who fixed it, but after a couple of days it
started rattling again.

I'd like some advice before I talk to the spray painter again.  Do I need a
new fitting?  Can I fill it with silicon to help stop it moving away from
the body?  Any suggestions?

Thanks
