Hi Chip, mostly original paint I think.
I know one of the rear arches had a rust bubble removed and the front bumper had some paint for stone chips. I think one of the previous owners was very handy with a mop, it has a few swirl marks but nothing you wouldnt expect.
As for the heat sheild, sadly no. The guy who owned the car had a friend who worked in the trade, he used the car I think as a test bed for the parts. I know he made a few of the heatshields as someone else said they had one... I know the car was around Southampton area if that helps mate. It is a good piece of kit! Really improves under the bonnet as the black plastic on the standard items always fades
