You have to ship them to Jet-Hot. Go to thier website for info. Ther are only 2 or 3 places in the whole country (IIRC) that actually do the coating. Mine was done out of MS, and I am also aware of a distributor out of AZ. They have a spec sheet you fill out, or can talk to a tech. You give them a CC#, and they set-up an account for you. Once they have your parts it will take 3-5 days.
