Car wash problems-gaging interest., getting to much water down the grill Options

[underthetire]

Gaging interest before I order. I want to make a magnetic "cover" out of sign material to cover my engine grill when I wash the car. This should keep a lot of water out of the engine bay, even just parked outside during a storm. I do have a sticker machine, so I will put the porsche name on it with "remove before flight". I have to buy a fair amount of the material to do even one, so if no one else is interested i probably won't do it. Thinking white material with red letters or red material with white letters. guessing somewhere around 20 bucks each.

PS i know a rain tray would solve it, but I don't like them.

I don't have much of a car washing issue, and still have the rain tray in place, but...

This sounds like it could be such a cool looking accessory if done well. If sticker design has no significant impact on cost, I'd suggest red with a black stripe and PORSCHE lettering exactly where it would be on the grille below, then the yellow "Remove before flight" caution across the bottom.

If I had photoshop skills - or photoshop - I'd try to mock it up.
