I have some sort of artisanal, metal, top oriented, window that essentially serves as a light well (but the room is almost completey dark, the main door is covered by a curtain because my girl friend don't like the fact she can be seen from people outside, even if the door isn't connected directly to a street).
This window, which occasionaly leaks water when it rains a lot, is just plainly put down on this metal architecture, which is rusted despite its paint.
Apparently, before we moved in the apartment something like 8 months ago, somebody seems to have removed the joint, which would been quite big or flexible.
What kind of joint do I have to buy, or is there some way I could craft one (I know I can't possibly craft one, but I can still do something now before I buy it).
Here is the window:
