In attempts to find a leak I've spent ages running water on various
parts of my wife's car. I'm now fairly certain that the problem is a
short vertical seam, running from a roof slot to the hatchback opening.
It seems to be a simple overlap with a couple of spot welds - the
question is how to seal it. Is there any body mastic that will wick into
a thin gap and then set? What do the body shops do?

Capt Tolley's creeping crack cure might be a way forward, it wicks
itself into a narrow gap.

My Focus Mk1 boot is leaking at both sides. Of course, the tail lights
are the usual suspects - but tests seem to indicate that they may not
be. I've got duct tape over all the possible areas of ingress - plus
over where the rear quarterlights meet the body. I'm now working on the
bottom (where the rear bumper meets the body).

However, I had my eye on this sealer in case I need it (but haven't got
any yet):

but I'll also look at Capt Trolley too (never heard of it before).

Thanks, from a quick look that seems worth a try

I've had a hell of a job finding the problem. I used plumbers mastic to
blank off different areas and build barriers - starting at the bottom
with a hosepipe and working up as each area could be ruled out.

Just had a look at your link - it's silicone!!!! Don't use silicone if
you might want to paint afterwards.

There are pukka car seam sealers that can be painted over - which I doubt
you could do with a mastic.

Hmm the problem then sounds like faulty manufacture. Trouble is that rust
has probably already started and with expansion and contraction and
vibration its going to be a big problem to keep it sealed.
Is the car very old?
These things used to happen a lot many years ago but modern cars joints are
a lot better.
