I use this stuff from 3M that is absolutely vile-smelling but delivers the same results as Sugur, for about 1/5th the cost. It comes in these little rolls, with an inner core material and an outer material, which somehow manage to co-exist on the shelf without curing, until you remove the end-caps which expose both layers to oxygen, somehow setting off the curing process .. you then smoosh it together, so it becomes this ultra-disgusting smelling blob, then apply it where necessary. Within a few hours, its like, rock-solid. I've fixed countless things with the batch I bought a year ago, and its still good after living in the fridge ...
