We are aware that on 9000s the drains from the air outlets can come loose and drain into the difficult area between the inner and outer rear wing skins behind the wheel arches. At Saabfest a splendid chap shared his knowledge and expanded my understanding of the issue, showing me behind the carpets in his car. More wisdom came from Mr Bayfield.
Not expecting a problem I whipped my carpets aside anyway, mainly to check the gulleys at the bottom of the wing skins and the strut top mounts. The strut areas are spotless, I found a couple of small areas of rust from carpet chafing, where the single (??) screw for the CD changer was once fastened to the floor (at the foot of that angled flange, not the dirty spot outboard of there) and at the drain hole below the left bumper mounting bolts.

Its all foreign matter apart from the bits near the lashing ring.
Irritatingly, three of the four mudflap screws have caused 3 cm diameter circles of rust. The fourth has a plastic plug with the screw driven into it. Why not the other three?? I wince each time I see a screw driven into metal on Wheeler Dealers with no precautions. Its unforgivable.

No rust in the gulleys, drains clear, although there was a lot of leaves/twigs/two snail shells down there and generally behind the carpets as if it was left outside in high winds in autumn with the tailgate open and carpets pulled aside.
Ground down the rust spots, used Hydrate 80, primer, paint, lacquer. The wheel arch screw damage is best left for someone who knows what they're doing and in any case, access is impractical from inside.
The antenna drain was just hanging in the void. There is a hole with a bung in it at the appropriate position and interestingly the equivalent hole on the right side was bungless so I transposed it. There's no evidence of the unbunged hole letting debris/water in.
I've dribbled Hydrate 80 into the gulleys in case there was any rust I couldn't see. Nothing's gone black.
What should I follow up with? Traditional Waxoyl?
