It’s a very common issue and usually just cosmetic.
It is often caused by the scuttle being steel and the quarter panel being Aluminium.
I think some years of Morgan’s are more prone. My Dad had a 2007 car and that had corrosion but I have seen other cars that are unaffected
BHM have one for sale for a good price given the paint issues
