wheel arch rust

Does anyone know of someone in the birmingham area who could sort out these scratches and dent in the wheel arch?

Malcolm - I've read your excellent DIY post for tackling wheel arch rust. I've noticed a small patch on the front nearside wing on the wife's SLK that needs tackling before it spreads to the outside. Is it just the silver hammerite that you used on your 230? Ours is brilliant silver as well...
