Powder Coating is fairly cheap also... I do my own powder coating. (mostly small items do to size of oven)
I can get a pound of powder for about $10 and it would do several Nerf Bars, or sets of wheels even.
Not to mention its a heck of a lot more durable then paint.
Some say you can't powder over chrome though (so you or they would have to sand blast it)
I have powdered over chrome many of times without any issues. (as of yet)
