Hekis do leak over time due to the fle of the body when travelling. It is quite a large, rigid shape!
You need non drying bedding sealer, which is like the sticky stuff you have on there. Names such as Carafa, caraseal, tiger etc have already been given - but it must be non drying and must NOT be silicone.
The reason it never dries, it due to the fleing of the bodywork surrounding it. Non drying sealer will move with the body and maintain a seal - whereas if it were to dry, it would crack and leak straight away. Most failures are cuased by old sealnt that has dried over the years.
As a temporary repair, it may pay you to get some UV stable repair tape from a DIY store - looks like thick scellotape - and stick this around the edge outside to aid sealing the heki until you can reseal it properly. As it is UV stable, it will peel off happily later, unlike other tapes.
It is handy to keep a roll on board for window repairs too!
