Powdercoating is worthless for rock rails if you are going to be using the rails for what they are made for. It's way too much money to get it done for something that will get scratched through to the metal the first time you hit the trail. It would be OK if it was for something else, but I've found the Rustoleum stuff to be durable enough not to flake off and very easy to touch out without it looking like you touched it up.
It's next to impossible to touch up the powdercoating and have it look decent.
Go to Harbor Freight and buy you a couple of these little thingies.
