Bottom picture was photoshop, but it came out beautiful (I want it to cure overnight and possibly add some clearcoat to give it a little extra shine/protection). I used a lot of tape so there's no drips, only in one spot where I did the letters, but that can be taken out easily.
The letters I used a touchup .5oz bottle (which didn't come out THAT great) but it still looks pretty cool. Otherwise I used a touchup can that autostores carry.
It's still the matte black plastic that it comes as stock (as well as the rest of the engine bay is) but it's still going to be noticeable and look better. I ended up also doing the ridges and walls, because it was easier to tape, and it'll still look cool. [wiggle]
