I took a couple of hours aside to clean up the underside of the car today and it came up pretty well IMO. It's not concourse but its pretty well solid underneath. An advisory on the MOT is a bit of welding on one of the chassis legs which I shall get done soon.
Any one know if this is likely to be the original factory finish, either way I'm pretty pleased with the results.
While its not mega clean like some I'm pretty pleased.
