I finally got the right tuit to investigate how the boot of my wife's
i20 was getting wet. Having removed the right boot trim panel and played
around for ages with a hosepipe I noticed that the offside roof trim
(the plastic strip that runs each side of the roof panel) is slightly
loose and I think this is where the water is getting in. I can't find
anything to tell me how the trim is held or sealed, or how to remove it.
Is anyone here knowledgeable about i20s? If not I'll have to take it to
a bodyshop.

It was the short joint that runs vertically from underneath the end of
the roof rail to the tailgate opening. I eliminated everything else
(with judicious application of mastic and hose pipe) then scraped out
the old mastic from the joint and added a tiny amount of black goop from
a (slightly) expensive large tube. Problem solved BUT I think the other
side is slightly leaking now :-) Perhaps the car's about to fall apart!
