Eternalbond tape, like all similar products, is only as good as the surface it is applied to. IT MUST BE CLEAN !
If you are really paranoid about leaks (paranoia can be GOOD is some cases !), remove that strip, clean underneath, apply butyl tape at the edge, re-install the screws (switch to stainless steel) with a bit of butyl tape around each one. This what they use on ocean going sail boats and they see a lot of water !
Although Eternabond tape is really good, the butyl tape and stainless steel would be a really good permanent fix. More work but the payoff is a sure thing without doubt.
