I'd go for satin black. You could even just lay a satin clear over the current coat. Flat looks like primer and rattle can gloss always looks like poo up close...mad orange peel. The best thing to do tho would be to body shop it and get it factory matched. But its not exatcly cost effective...front lips pretty much exist to get scratched up...

 

^^ I agree so.... satin black with a satin clear? My last lip on my black car I tried the Gloss rattle can black and it looked like crap

 

you have to apply it properly at first. Once it's fully dried then wet sand and polish. It'll turn out very shiny. Only downside of using the rattle can method is the amount of paint applied. When compared to a paint gun it's significantly less, therefore to compensate you have to add more layers. Also, a UV clear coat is a must, otherwise your finish will fade and turn ugly.

 

Rattle can the intercooler mesh!

As for the lip, go OEM, or gloss black, like someone else suggested.

Side markers look alright
