I've powdercoated almost everything under the hood on my 1999 DII over the past two weeks during my motor swap, 4.0-4.6. I chose british racing green, gloss black, and yellow highlights. My wheels are gloss black as well. Got a prototype steel bumper from DAP unfinished and will be customizing it and powdercoating black also. The plenum is green, intake makifold is green, valve covers are black with green stripes, oil pan is green, water pump is black, pulleys are all black, front cover is black, oil dip stick holder is yellow, etc. etc. I also ceramic coated my exhaust manifolds silver. I will have pics up VERY soon. I gotta get the motor running first!!!, but you may be able to see the benefits from powder coating after you see how well the engine and wheels came out. All the work was done by Precision Powder Coating in Anchorage, AK. Look for the post in the next few weeks...
