Cheers for the advice guys. I think I'll just give it a very soft clean in the undamaged areas as suggested then seal it and leave it like that.

I will have to fix the blue score panels tho (the pics don't show it) but a couple of them have part of the blue paint burnt/rubbed off which I think will be quite noticeable, plus I think I can address that with my skill level, the other parts not so much.
