I have a couple of trash and recycling wheelie bins that are starting to
fail. I will attach a couple of mending plates and try some hot glue.
The generic glue sticks are EVA which may not bond to HDPE. The
replacement costs for the bins are only $70 so I won't spend a lot for a
welding kit or hardware.

Anyone tried any of these type products?

Ebay has car bumper repair kits.
