The reverse hood scoop will be nothing but trouble unless the intention is to create a "show car" and not one that actually works. They are OK if you run just a dozen days a year and have a unlimited team of scientists/mechanics/climatologists on your payroll but in real life you have opened up a lot of problems.

Ask a detailer like "bunny" what, in an engine compartment should be "bagged" before any water is introduced.

For one thing have a spare alterntor in hand, it takes not much more than a few rain drops to F up.

The reverse hood scoop should be reserved for cars where heat evacuation is actually an issue and not for cosmetic reasons, your engine is probably more efficient at the designed tempurature. You have slowed your car down.
