I disagree. Goop is very flexible when cured. I think the Goop should be sufficient for this application, although I do think the 5200 would provide a stronger bond, as it is designed for through hull applications. There really isn't a lot of water pressure that will be going on where you are planning to use the product. With that in mind, I would prep the surface really well by scuffing it with a heavy grit sand paper and cleaning it with acetone or alcohol, and I would go with the Goop because of its great flexibilty when cured.
