Hi, I'm just in the process of taking the wings off my MGA in preparation for a respray. They a reasonable but the flange at the wheel arch is starting to rot. Although the outside off the wing is unaffected just the flange where mud can sit. Is it possible to repair this by welding a strip around the arch or will I need to cut into the wing and splice a repair panel in. Obviously I would prefer the former as it involves less work. Has any one experience of doing this ?
