During cleaning an oven today, the paint started to come off around the edges of the door closing area next to the seal

never happened before! Seems this part must be anodised aluminium but would have thought enameled as usual.
The job is for an estate agent who we do regular work for.
I am going to inform them tomorow as to what has happened.
Does anybody know of a paint that can be used to correct the situation.
