Cheers Lewis, I think I might hold out for a new one at the moment, I have a used one but the pitting is noticeable with the paint being so thin. I know they're rough to begin with but comparison to the new one I have for the right side its quite noticeable, although I should point out I'm rather OCD so perhaps the normal person would never notice.
The one I have was cleaned up from a similar state to that one so I don't fancy doing another at the moment. If all else fails and you still have it, I'll come back to you.
