I had a set of used Hookers in my drag car coated by Jet Hot, then more than 10 years later when I had the engine out to freshen we had to modify them a little. The coating wasn’t too bad, but showing it’s age. I called Jet Hot and they coated them again for free ( I paid shipping ). I explained to them they hadn’t been new to begin with, nor was I unhappy, but they still said one re-coating would be free. They held up pretty good again for quite a few years until I accidentally bent one in an unfortunate trailer incident and I replaced them. I had a couple other sets of headers, and a couple sets of long cast 427 manifolds coated by Jet Hot and was happy, but since then people have reported Jet Hot has been sold and their quality and customer service have not been good, so I decided to try a local company that had good word of mouth this last time. Short answer, yes they were able to remove the old coating & re-coat them.
