    I'm sure I saw a thread on here a few months back about using silicone at the end of the A pillars to stop leaks (seals are insanely expensive from the dealer)..

    And the boot leak, probably worth unblocking the drain holes so the condensation/can waiter can leak out. There's also a draining channel that can get blocked with leaves/debri and cause water to run into the car, so probably worth a look.

    Other than that i'd recommend the Autoglym hood kit - been using it for the past couple of years and just recently bought my second pack yesterday and re-proofed my roof

    Try searching through the member "Pangster"s posts. He's the Z3 guru on here. If anything you could probably get some inspiration from his car

    ta altreed,yeah read that ! thanks tho but we dont think thats the problem(we think),water seems to soak straight thru skin??? will treat it roof
    also we had to pressure wash around boot seal to clear muck and grime and water now drops into channels and comes out bottom of rear wings,but we will force compressed air down channels to make sure,but there seems to be a lot of condensation inside bootlid so much so that when u slam boot down water pisses out of bootskin channels out over the rear bumper

    If you open the roof, and take a look at the top/end of the A-pillar rubber seal, you'll see an indent/plug which can crack around the edge. Water running into the windscreen discharge channel that should head south and away is channelled along the side of the car and exits at the first join of the soft top and onto the seat.

    Best stuff to use is Gorilla glue. Expensive for the amount you'll use, quite literally a dot, but does the jobe better than anything else...

    Hi, (virgin member here) did you ever resolve your roof leak problem? Just bought my first soft a couple of month ago. It appears that the roof is completely covered front to back with condensation. The boot lining in fact is not too back actually (only very slight condensation). This is spoiling the driving experience having water drip on your head whilst driving.

    I've seen the thread regarding placing silicone in the pillows at the top of the windows where there is 2 rubber bungs/grommets?!?! Im going to place some black silicone in these but as regards to the roof is this just a case of treating the roof with some of the renovo or auto glym??

    Or is it a case of driving around like a local thug having to constantly wear a hoodie??

    Any help would be massively appreciated.
