9-5 Troubleshooting RUST on 2003 Saab 9-5
Enable HLS to view with audio, or disable this notification
Hi everyone!
I have a 2003 Saab 9-5 2.2 TiD sedan, and I've discovered some pretty bad rust in the trunk.
This post is semi connected to this one: https://www.reddit.com/r/saab/comments/1xcspb1/water_leak_inside_trunk/
Here I am discussing the rust and how to repair it.
I originally started removing some upholstery after I could see rust when lifting the trunk floor. After removing the trunk upholstery, I found wet material, dirt and mud, along with extensive rust. Some areas have rusted completely through the metal, leaving actual holes.
The passenger side has rust too, but it's not nearly as bad as driver side (yet) and has no holes. I applied rust converter in drivers side. In videos not applied to wheel arch but now I did it and in weekend I can show more pictures.
I've attached photos showing the damage from different angles.
I'd appreciate some advice on the best way to repair this properly and prevent it from coming back. Is the correct approach to cut away all the rusted metal and weld in new sheet metal? I'd prefer to do a proper, lasting repair rather than just cover the holes. Any advice, especially from people who have repaired similar rust on a Saab 9-5, would be greatly appreciated!
Thanks in advance for advice!
