hello there ive had my 99 disco 2 es for about 6 months now it was ok at first but then rain started coming in through the sunroofs so ive now sealed them up still rain came in i noticed that the sponge/ rubber gaskets that mount the roof bars didnt look to healthy so i sealed round them rain still manages to get in should i now seal round the outer edges of the sunroofs & even the curved roof windows i intend to remove the headlining next spring to see if i can cure the problem and get the sunroofs back to normal thanks for any advice
