SLOWING down the rust monster..........

We used Ospho on my sons Dart to stall the same issues. Cleaned out the rear quarter/trunk drop area as best we could with an air hose. Sprayed Ospho in there until it was dripping out. Pulled the rear seat and rear door panels and did the same thing, until it was dripping out of any gaps and the drain holes. Ospho is a rust convertor, so its supposed to stop the rust.
