So since I've installed my new grille I've noticed there is a lot more room for small rocks and whatnot to fling up and hit my radiator.

I was wondering if anyone has setup some sort of protection so the radiator doesn't get banged up...

 

You could try to mount some type of a dark colored mesh behind your grill?.....

 

get some plasic screen(the type used in screen windows and doors)and secure it with some small zip ties.

 

If you get a rock ? just play the odds and let it roll
