Paint blistering on door

[Kilbroneyxkr08]

I have an azure blue 2008 XKR 4.2 which has a small patch of blistering almost at the bottom of the passenger door. Can this be treated and the door repainted? Will it reappear? Is there anything to look out for because it’s aluminium?Thanks in advance for your help and advice

Hi Patrick, the first thing to appreciate is that aluminium does corrode in the right circumstances, but it produces a white powdery residue, which can obviously cause surfaces to become irregular. Aluminium can be treated and repaired similar to steel body panels, but the body / paint shop must know what they are doing and treat the panel correctly before applying the paint and lacquer.

Do you have a notion as to the cause of the blistering? Has it spread from a stone chip? In all cases of aluminium corrosion I have come across, the start point has always been where the paint coat has been broken.
