Rust on the sunroof, and sunroof only. Metal experts??/

[passat TS]

[ Converted text/html to text/plain ]

Huw,

I do have very little rust around the holes, exposed metal.

The rust are in a form of very small dots all over the sunroof, close and far
from the holes.

Also, I didn't have any sign of this rust before sealing the sunroof with the
fasteners.

So, based on your observation, I could be stuck in a corner.

At this point I'll try the washers, unless a metal expert comes with a
explanation.

Anyway, thanks to all the help.

Carlos.
