I looked into this myself. I'll share what a powder coat guy told me. He said...if you run them wet you can get away with powder coating. Which his cost would have been $180 for both. If you run them dry they would have to be ceramic Coated which was approx a little less than double the cost (I think). BUT...he recommends having the chrome chemically removed which at "his costs" was about $200. Additionally neither of the coatings looked nothing like chrome even tho they were called "chrome". This is just information one guy told me, not sure if it helps. I might be looking into rechroming mine at some point.
