Rust around rear brake lights

If it’s the bootlid you can see detail in the “MK3 galvanised” topic

Are mk3 on a 2009 plate fully galvanised

My model of MX-5 is: __Mk3 I’m based near: Sheffield I’m looking for technical help or recommendations on: paint defect / Galvanised panels I have recently brought my first MX5 and it appears to have a paint defect on inside of the boot lid . My question is : Are 2009 plate MX5 fully galvanise and any idea what caused this defect as the substance underneath appears ok but don’t want to disturb it to much ? There no obvious red rust external or internal or on the outer boot lid. Many Thank…
