Try epoxy (or liquid weld). Don't know how familiar you are with this product but it comes in two separate containers. One is an active agent and the second one is a hardener. Strong and durable stuff. I use it on my car mirrors, pipes, tent poles, cameras and kayaks. Just be careful how you use it and become familiar with any cleanup/excess removal methods before you mix the stuff. <br><br>Tip:<br>Just as with the silicone, if your fingers are wet (keep a cup of water handy) epoxy can be molded without a problem. So if you need to wipe out the excess just wet your finger or a paper tower. Be sure to use a lot of water. But try first with something you don’t really care about and be careful with amount you mix. I always have lots left over when I’m done and it has to be thrown away.<br>
