Karl,  I see from your picture that you still have some fiberglass
insulation in there.  I would strongly recommend you replace that with
something else that does not hold water.  I replaced mine with some
aluminized bubble wrap type insulation available at Home Depot.  BTW I too
use Krown or Rust Check very liberally and it's great stuff to stop the
rusties, but you realy need to take the interior out to realy do a good job.
