I'm just going low budget pop rivets and sealant. I have this Sikaflex 295 UV stuff that is amazing. Luckily none of the stacked hull welds were fractured. It is not a long term last forever fix, but can be rerepaired at a later date. I think it is mostly bait at this juncture. So tough guy vandals say hey we trashed that, we will get it better this time. Then Dave gets them. If not, it should at least float and catch gsf.
