OP, While the advice above is good you should use the exact same sealant as the factory used until your warranty expires. You don't want to have a potential warranty denied issue.
On the other hand, when I asked the service adviser about warranty coverage on factory-installed caulking he said that they don't consider claims before a failure unless it can be proven to have voids or gaps or whatever.
To my mind, I am not waiting for it to leak before I fight with the warrantor over leaks. I'd rather put on the Eternabond if the weakness is significant, get no leaks and never have to worry about arguing with the warrantor. Besides the warranty only lasts 1 maybe 2 years.
