Anybody ever make your own hood scoop plug?

I bought a big piece of foam on Amazon and cut it to fit my 6-pack scoop. Tucked in between the air filter and front of the scoop. I just wanted to keep rain and crap from getting all over the engine/compartment.

Rode from Detroit to Florida that way when we moved and I brought this car down on my flat trailer. (Pic also shows the "shield" I threw together from an old pickup truck bed mat to block crap from going back and hitting the car.)
