Will this epoxy work on a Kayak made of polyethylene? There is a crack of 6 inch on top of kayak.

It will fix it, recommend you have a patch of rigid plastic you are gluing behind the crack to give it more rigidity. Something that can flex will give it trouble. It will leave a rough residue after it cures and shrinks which you can sand down.

Will this bond aluminum to hdpe for below waterine use? if not which product would you recommend

I can’t answer your question directly but I used it for HDPE to HDPE and I think it worked. You can mix a small amount and give it a test. I would definitely degrease both materials well and sand them with rough paper too.

is it waterproof? Flexible?

After the long curing period..... it is water proof and semi flexible

Is there a dispenser /applicator to work with this?

Do not use the dispenser advertised with this product. The plunger has two sides and the smaller of the two is too large for that side. False information.
