I've had powder coated Westin bars like this since 2003. No rust issues. Available at Auto Anything linked in a previous post on this thread.

I had the ones you have on my 2005 and replaced them with the one I linked on Auto Anything. The reason was they rusted....from the inside out. They still looked great on the outside but you could literally just about push your finger through them in places. The problem with them is that they are open on the end mounts allowing water inside. They are not powder coated inside.
