how to weld polyethylene??!?!??
I have just purchased an old town canoe for a good price, but it has a small crack in the floor, just thru the inner layer of polyethylene into the foam core... I talked to old town and they have an adhesive epoxy that they say will fix it 100%, but I would feel much more comfortable using something that will actually rearrange the molecules together?? I'm looking for either a heat weld, or preferably a chemical solvent that will "melt" it back together? anyone have any ideas on this? I have no idea what will melt a kayak/canoe, if anyone has ever intentionally or accidentally found what will dissolve polyethylene, please let me know!?
also, if anyone knows where I could get pieces of plastic from an old town canoe that I could experiment on, that would be very helpful too!!!
thanks in advance, I know this won't be the first question like this!!!
