Hey I think ceramic coating is great and have used it but if you dont want to spend some big bucks, I would try Slip Plate spray on grafite coating. It comes in a spray can and only cost 4 or 5 bucks. I used it on my 71 Demon manifolds and so far I really like it. I read about it in one of my muscle car mags I get. I picked it up at my local NAPA. Good Luck!
