I am thinking about buying some of those D-ring anchors from MEC for my discovery 169. How can I secure these in? Vinyl tec says it works with pretty well everything, but it doesn't mention polyethylene. Does anyone have any experience with this? Also, my canoe manual says I should polarize the hull with a propane torch before attempting to bond anything to it. What is that about? Is that necessary?
It is Royalex. Makes no difference though, the primer is key to prepping the surface and the ABS/PVC cement chemically bonds like integrates permanent sort of thing. I attached my foam knee pads permanently in place using the same stuff.
