Right so to the problem, i recently bought a Mini city e with the intentions of restoring it. And whilst i was doing some work on the front end of the car my dad (as they do) proceeded to poke all the areas of rust with a big screwdriver and when he took the back bumper off the right side basically fell away without the need to undo the bolt, therefore the whole of the right side and partially the left side of the lip which the bumper sits on has rotted away and there is a big hole.
Also the area above this and to the right has a hole in which goes through to the boot.

I was wondering what would be the best way in which to sort this as i have no intention of putting the bumper back on? And would it be ok to fill in the hole to the boot with fiberglass moulding?

Your help would be much appreciated guys.
Thanks Scott
