hi allan. i appreciate your input and accept that glueing wont be an option, as advised. ho hum..tw
I'm no rocket scientist, but tripping, I think you're all wet.
As Stringy pointed out, some of us here have been using 3M Scotchweld DP 8010 and DP 8010 NS for a few years now. Here's an application used as a structural reinforcement in a high stress area that quadrupled the life span of the old cam column design:
Here's a permanently bonded drink holder:
Six months shelf life refrigerated? That's what they recommend, but these projects used a batch stored about a year at room temperature; no detachment whatsoever.
Not a 3M fan or can't get it? Why not try Loctite 3030, another excellent HDPE bonder. Need to seal and reinforce a leaking drivewell stress crack? No problem:
Here's a recent project, a flush mount PE drivewell plug for soloing the new Oasis...
...glued to PE spacers and the original drivewell plug:
This was a fresh batch of product -- made in 2007. I just did this project last week (I do keep it refrigerated though). Even works way past its expiration date -- imagine that!
Strength: Here are a couple of HDPE sample disks that I smeared some (fresh) 3030 on. They were unprepared (no solvent, cleaning, sanding, pressure, etc). Here I tried to separate them with pliers and only succeeded in breaking one of the disks:
The only way they could be separated was with a hammer and chisel:
If you will examine the separated disks, you will see that none of the glue detached from the PE bond on either piece, but ripped within the glue itself:
I hope this has provided you with enough specific information on products and projects to spur you on to actually try one one these excellent products.

i'm very interested because i've a fantastic idea but without the means to attach it to any kayak hull, its actually a useless idea.
Looking forward to seeing how your fantastic idea turns out!
