I had to seal the front part of the pop-top (the luggage rack part)
completely because I put a sunroof in it (cut out the rack, put adapted
piece of doorskin underneath, fiberglas top, paint, cut out and install
sunroof, cut out front roof, and clip with moulding). I simply used
silicone: no noises, no leaks, cheap. You can install it invisibly by
lifting the top, applying a thin bead to the gasket and re-installing it.
