What does your bay look like?

My opinion........

Don't go body color unless its a show car...
Don't go body color if you can't keep your engine as clean as the outside of the car.

It looks cool when its first done but mostly looks like crap after some real world miles.

Go with one of the stock engine colors and you will be able to touch up things anytime.

Though I like original scheme, this guy's right.
If you 'really drive' your car the compartment gets grimy after a while.

pressure sprayer works good.
