So as it is going to be a while before it gets installed, I thought I'd clean it up a bit and share the results with you. Pic 1 shows some of the baked oil on the gearbox, and my tool of choice - a bog standard drill with a 2" wire brush. This did a superb job of getting rid of the crud on the gearbox, although I could not get into all the nooks and crannies.

Pic 2 shows halfway though the job - the darker areas ar those I have brushed.

Pic 3 shows the finished product: I did the nooks and crannies with fine wire wool (wach out for the little bits of metal getting everywhere) which resulted in a superb polished finish. So I did the rest of the box with wire wool and it looked very 'bling'.

To protect it I sprayed it with WD40 and gave it a good wipe down. This gave a nice semi-matt titanium-like finish. In all it took about 2hrs and was by far the easiest of cosmetic jobs I have done on a car.
