I would have thought the original coating would be something like 3m body shutz or stone chip, which is more silicon than wax based. It is rubberised to resist stones chipping the paint when thrown up from the road.

 

As Bowders has said, Hammerite is a good place to start, as the panel should be galvanised from the factory already unless any body repairs have been done before.

Kurust then silver hammered hammerite

Sorted

Ive just done what bowders advised, used a stanley knife untill it had some restance to the bodywork, cleaned it up and paint black hammerite smooth and will touch up later with silver hammered.

1st coat.

If you slice the overlap at a angle with the Stanley knife you can avoid the difference of lip where old sealant is. i.e make it flush

 

Sad I know but i am fussy like that...  :p
