There are so many products promising the earth with rust conversion and inhibition that you start to get sucked in to the notion of a quick fix from a bottle. I was getting close to purchasing RustBullet to try and arrest the rust on the rear arch.
I suspect with the inner and outer rear wings rusting from within the join inside the arch that I am not going to easily repair that without a welding job. I'll let it get considerably worse before I go to that effort though
Any advice on the best way to slow it down?
Maybe try and inject some waxoyily stuff between the inner and outer wing. Maybe try to do it from inside the car, i could imagine that you would be able to access the area if you remove the subwoofer.
