I have a Series 1 RS low mileage in excellent condition etc, the only thing letting it down is the finish of certain engine parts.
Over the years some of the metal bits eg Manifold, Injection housing,
have gone a bit discoloured / oxidised.
Whats the best methods to tart them up? Can the manifold be painted, and what should the colour be.

Anyone got a spare pipe so I can get rid of this damn dump valve as well!!!
Any advice would be appreciated.
