Freelander 1 leaking roof

Another leaking sunroof story, This will be the third time I have had to replace this sunroof 1st was new seals all round plus new mechanism 2nd complete sun roof replacment , and now its leaking again rain pouring in on drivers head,
Has anyone just sealed a sunroof shut with silicon does it take and does it last

Black silacon jam nozzle and squeeze away no more leaks. But no sunroof small price to pay.
