I'm amazed at the abuse that Jet Hot coating takes. When I bought my Sanderson headers, they tried pushing their coating - my comment was that I "knew" Jet Hot, but had no clue who they used. The woman (the owner) got a little snarly with me, but it was my choice and dollars. By the time I was done with them, it probably cost $50 bucks more

Mine were done in Mississippi



That's after a couple of seasons, with the photo taken since it was put to bed for the winter and haven't been cleaned (even yet)I also had the intake done with Jet Hot. It's real easy to get gas stains off rather then trying to clean raw aluminum
