I really don't know what to say for this simple DIY...
First of all, take out the grill

Next, grab a can of Smoke paint by Tamiya or Pactra...

Prep your grill by washing with a light soap and water... like hand soap. You don't want anything that will be abrasive. Next, fully dry the grill. Paint will not adhere to wet spots! Take your time here.
When it is fully dry, take a lint-free cloth, microfibre cloth or a compressed air can and clean off any particles left over on the grill. Once it's as clean as you can get it, bring it to your paint area. Watch where you hold it... your hand oils aren't good for painting either.
LIGHTLY spray over the chrome areas. Your BEST bet is to do four to five LIGHT coats. As with any painting job, less is more. A lot of light coats is better than one dripping wet coat.
You must let it fully dry before you judge the color. Give it at least 15 minutes to dry and darken. Let dry overnight.
If you'd like, lightly overcoat your work with a glossy finishing spray (no recommendations yet... Krylon?). Let dry one more night... then you're all set!
This isn't the best picture, but you can see the difference between the outer lip portion and the retaining clasp color. I purposely let it go with a semi-matte finish, rather than glossy.
I'll add a car pic soon. When you have a chrome and a dark chrome one side by side installed, the difference is stunning.
