Cured in the bottle? Some how it got opened before you got it. It cures with contact with water vapor in the air The other polyurethane that is very good is made by 3M and called "3M 5200" It is sold as a marine adhesive. One thing you can do with this 5200 is install a through hole sensor

You CANNOT expect any high-strength bond on HDPE that rivals the strength of the material, not with any glue. Typically it is bolted. E6000 (same an Amazing Goop except uses PERC solvent instead of toluene) is the highest strength. Locktite makes a system for cyanoacrylate where you use a

In general, no matter what your glue question is, my glue answer is epoxy. HDPE is almost as difficult to glue as UHMW or Teflon. Very low surface energy. I'd recommend cleaning with isopropyl alcohol to remove every trace of oil from the surfaces (HPDE and panel), allow it to air dry, and

I think there is some super high end glue that 3M makes that will glue HDPE, but most people don't bother trying to glue it. I would consider stapling velcro to the HDPE strips.I've had very good luck using the industrial strength velcro that 3M sells, not the Velcro brand. I've mounted
