Just an FYI for those that may read this, as it seems you already have the fix in place. I have found a product that is called flow-able silicone at O'Rielly auto parts that works different than any other silicone I have used, and I've used a few. It will flow down into a crack as advertised and seal very well. I have used it to repair a leaky rear windshield on a car I had and to reconnect a lens on the wife's old minivan tail light. Never had to re-visit either one and it doesn't cost you the farm. Just remember to have it upside down so the gravity will pull it down into the problem area.
Creativity is just intelligence fooling around
