Cain has got back to me and unfortunately there is nothing he can do to help although he could see why I had tried to polish out the 20 years of scratches. He suggested painting it the colour of the car which is silver in my case which might be very nice and others have suggested covering with leather, a wrap or just polishing all the turning out for a glossy look.
I'm considering these and will do something with it when I make my mind up but just live with it for the moment as a reminder that polishing isn't always a good thing!
