You using our accessory mount? Then the Scotty bolted to that? That would be required because of the soft radius of the tubes.. You need the radius and a large surface area to get the glue to hold. These things glue on like...permanent, so hard to imagine coming loose if done right. Use the glue provided with the kayak repair kit or with the accessory mount. Wet both surfaces, tack dry, then press together.
