Marine Goop on Polyethylene....

Pro-Poly HDPE glue, and Poly-Weld adhesive, both advertise to be structural and "permanent" but I've not tried either and I'm not sure what type of bond they make with the plastic

You may be correct, there may be a couple products that create a chemical bond. It's been a while, but I do recall reading about them, but the products were not available to the public at the time, and my buddy that works in the space industry was unable to provide me with any information, or product. That all could have changed by now. However, I would be cautious about the bond created, as to it's depth and strength, considering the thickness of these yaks. But keep in mind, that an adhesive is just that, it sticks, but does not create a chemical bond, as a true glue does. (for those wanting to get technical, yes there are glues that adhere to pours and create a bond that way, but that does not apply to polyethylene).

[QUOTE=Big T; So is the mechanism that keeps my FF transducer on caused by suction? Or gripping onto the pores in the plastic? [/QUOTE]

It sticks, but it does not create a chemical bond, as such it is subject to releasing it's grip. This generally happens a little bit over time. I've used Goop in the past on poly, and after a few years, i could grab an edge and pull it lose; it did take some effort. Cleaning it up good and re-Gooping fixed it for a few more years. It's simply something that you need to keep an eye on from time to time.

Rocket science does play a role in the formation of a kayak and the adhesion of many accessories. Quite a challenge at times. Perhaps marine goop could be replaced with the new "super duper glue"?.

Does anyone have experience with this product? Also, when given a choice of being plastic welded or using this gflex product, would anyone opt out of the plastic weld. Reason being: I have a few minor holes I would like to fill
