Engine compartment paint color?

Absolutely do it body color. No reason at all to go the black "Chebby" route.

Sure you can get black spray cans and this makes it easy and cheep..... But did you know you can get body color spray cans for a little more?

Go to a paint mixing house or a NAPA that mixes paint. They can scan the color off the body and mix exactly what you need into a spray can.

A little primer, some scuffing and your engine compartment can look like a million bucks for fifty bucks.
