While it may not help, you should use plain silicon spray to condition the gaskets. I generally go over all over the gaskets yearly ish on all the cars.

For this leak you might be able to pop the top, check for any debris, missalignment, or curlying of the gaskets, clean it good with silicon spray and then reseat the top.
