Hi I've noticed my 2.5 begining to rust at the back

where the pucks are I suppose you could call it the rear cross member area. The front edge of my bonnet is rusting, the door top edges seem to be going in one area with those rubber things curling up (have newer doors and bonnet seconhand to fit when Ive got time) and around the sunroof.
Oh and the front bumper is so evenly rusted all over that I wonder if the guy who had it before me was going for a rusty bumper look! Again I have another (normal painted) to replace it with
Considering its from 1998 I don't think that's too bad.
The brake pipes will need replacing according to my mechanic before next years mot as they have some corrosion on some of them.
