I rattle canned mine (flat black rustolium), and I will do the same on my upgraded sliders when I put them back on. Powder coating is nice but it adds to the price and there is the risk of damage in shipping or on the trail, if you paint them yourself you can repair as needed without anyone noticing.

I have two sets in bar metal ready to go anytime, I am having the steps made (waterjet is backed up 10 days) and if you want them you have to wait a little longer. If the steps are not wanted they just need to be crated and shipped.

The steps are a nice added feature and I will have them added to mine which is why there are no sliders currently on my Jeep.
