1998 1.8 Xei FreeLander 5dr HELP!

[John182rs]

Ok as above that is the car my mother dear... Has.
Its the one with the massive black bumper or rub strips around it.
Now my problem is that she has tried to use back to black on them, an its faded and ran streek marks down the sides of it and its impossible to remove said marks from the grey plastic when its meant to be black.
Now ive tried every thing to get it to perfectly grey ish again so i can use plastic and vinyle care to restore them.

So can anyone tell me how to remove all of them from the car.
Rear bumper
Front bumper
Wings strips (both sides)
Door strips (both sides, back and front)
The little bit on the back door.
And basically any thing else.

Im after doing this so i can just get them resprayed in a matt or satin black.
I would do them on the car but i cant get the car in the garage area that i work in.

All information is appreicetd (spellings rubbish sorry). An ill post pics before, during and after.
