    Different Coupe Leak Fix

    Something else to try if you haven’t tried it yet.

    Ok guys. Your pleas of woe have spurred me into action. I rarely post but felt Paul N. might be near crisis point with his wet coupe.

    I spent an afternoon recently with a hose pipe, an airline and a tube of the rather sexily named ‘3M 08509’, a non hardening auto sealant.

    I had the headlining edge pulled off, loads of trim off, sunroof in bits etc.

    Surprisingly my sunroof was not leaking. I had thought it was. Luckily my windscreen area was ok also.

    The major leaks I found were getting in on both sides from under the trim arrowed in the pic and through the roof rack insert areas.

    What I did was to gun in some sealant under the trim arrowed (from the top side after drying with the airline). I also removed the roof rack inserts, squirted a bit of sealant around the holes, then replaced the inserts. Rub off the excess with a rag and job done.

    If you’re wet give it a try. Worth a try if you’re desperate I’d say. I can’t remember this particular leak being mentioned before – hence the post. Do post and let me know if it’s helped anyone.

    Cheers for the advice there Nigel, I need to sort the leaky old girl out sometime, luckily I don't need her as an every day ride but might do in the not so distant future...

        where did you get the 3M 08509 from Nigel?
        I'm going to try pumping it into the tops of my a-pillar trims and see if it seals the fecker before i put the interior back in

          Brilliant post - anyone solving leaks on Coupes deserves special credit. Thanks for that - I will have to investigate on mine as it is reaching crisis point.

            Sealant

            @ Error404.
            I got the sealant from a mate who works at a bodyshop.
            I guess it's widely available. Google it?

                wonder what the difference between the one you list and this one...Linky

                But, isn't this just that horrible sticky black windscreen bonding adhesive - comes in a cartridge...?

                Good luck getting that neatly under the trims...!

                  the more expensive one is for bonding in the screen, the other is a non-setting sealant that stays sticky so it doesn't dry out and crack etc

                        Something I discovered that might help others.

                        My damp Coupe boot can be cured by removing the spare wheel. Not ideal if you are out and require the spare, so I carry an RAC card at all times.

                        It seems that the spare wheel distorts something at the hatch enough to let water in.

                          Well I've now had a water tight coupe for a week

                          Combination of spending hours aligning the doors, wondow mechs and rubber corner trims perfectly and gunning some of the 3M sealant listed above into the tops of the a-pillar trims and along the top of the windscreen corners. I used to have about 1/2 a litre a week coming into each footwell - now bone dry for a whole week even during the torential rain we've been having

                            Do you have to remove the trim to add sealant? I think that’s where mine is leaking from
