I found this stuff on Amazon for less than $12, so it wasn't that much of a risk. http://amzn.to/2ku8pKd
Here is a couple photos of the: Sporthfish Cowl Body Armor Powder Coated Finish Outer Cowling Cover for Jeep Wrangler JK Rubicon Sahara Sport X & Unlimited 2/4 door 2007-2015
The color is a muted black, not as deep as I would have wanted, but you can't beat the price. Make no mistake though, this is plastic.
