Cali EV - Paint shop in the east midlands

Does anyone know of a good paint shop that can fix a small amount of rust on a near immaculate front mudguard at the bottom edge. I got it from someone off here but its maroon, so it needs matching the colour of my Blue 2001 EV?

Bernard the Guzzi at Oakley ( near Bedford ) bike night Thursday where I ended up queuing for food behind another nice Guzzi owner. Given 510 bikes there and I counted 6 Guzzi’s, what is the chance of that!
