Got fed up of the boot topping up, so decided to hunt down the leaks. Took off the roof rail, in true Landrover fashion the last screw was a total tw** and had to be drilled out, impact driver wouldn’t shift it. Removed the hard top to find the seal was in very good condition. On inspection of the hard top I found two channels that run front to back on each side of the top, one of the channels is just pattern, the other is where the sides of the hardtop are joined to the top and are fitted with a seal. There was water marks on the inside of the side windows, so these seals were leaking. You can get to these inside the hardtop but it looks a mega job to remove all the lining etc. I decided to seal them from the outside using black Stixall sealant (£6.17 delivered by Amazon) started at the front and filled the channels and run it down the back to where the hardtop sits on the car. Noticed a leak at the back window so I filled the gap on the plastic cover that the rear window tucks under. Checked the boot this morning and totally dry after a night of rain. I was attempting to buy a hardtop seal prior to this repair and luckily enough, no one had one, saving £100 plus. If your leaking, give it a go, only costs £6.
