well thanks to everybody for their insight and suggestions, I don't like Wrap for it can come Unwrapped at the edges and corners.
The HotRod black seemed to be a good way to go but cannot get it here in the UK.
Amzon do list it, but its out of stock and they don't know if it is to be In stock in the future.
Luckily I made a call to Johnny Woods who has given me the details of a Lachler paint which is very good.
I must say that if its recommended by Mr Woods the results will be correct, having seen some of his mangusta restoration work, its just stunning.
thanks to all once again Peter.
