hope you are able to offer a little advice to prvent a small problem growing into a costly one.
We recently had our car restored but as it is a mini we knew we would still need to keep on top of it regarding rust. We have a small area bubbling up under the paint, it is on the top of the passenger wing where it meets the windscreen scuttle area the curvy bit near the door facing up to the sky);
We had put some clear waxoyle down there but obviously not done a good enough job, is it easy to repair? As its fresh rust I am going to assume it will be surface rust under the paint so hopefully sand back and repaint but just wanted advice on what can be done to stop it?
