I will be doing Dunc, once I've collated all the pics of 360's restoration and written it up in the 'projects' section.
Mine looked rotten, so much so the MOT tester said it would be an 'advisory' on the next MOT due to rust under the radiator. However, once bead blasted it looked new! The rust under the radiator was just heavy surface rust and you'd never know it had been there now.
The subframe is now painted in Porsche 'Fashion Grey' which is similar enough to the original primer colour.
