anyone have any simple solutions to seal them?

I can see where it makes my hood insulation sag and it ends up sitting on top of the fuel lines and the moisture then runs down to one of my spark plus wires and my car runs like **** at that point...its only when in heavy rain but its still pretty damn annoying

 

Sounds like a good opportunity to buy a new hood, this time with heat extractor or functional scoop! ;-)

 

Remove louvers. Neatly schmootz some silicone sealer on the louvers where they meet the hood. Reinstall louvers.

 

Is there a certain type of silicone you need to use? I'm doing this on my car too.
