Thanks Jim - good suggestion/procedure. I hate doing bodywork but I'll be getting on this with this later.
One of the problems in this particular area is getting into the edge fold where the old sealant has been,so a bit fiddly. I think this is where my original treatment 2 years ago has gone wrong.
I can see another `pimple' a little further in on wing panel - doesn't show on photo. It lines up with one of the internal spot welds on the panel strengthening bar so I think it has migrated through from there. Another area worth checking when you do yours.
