It appears that Jet-Hot is a service business and not a product that I can buy. They may have their own proprietary coatings but it doesn't appear that they sell them as a product but only as a service for which I'd have to send my stuff out-of -country to have them apply it.
I can get it done here in Canada by any number of businesses that use a variety of products including Cerakote and Ceramakrome. Unfortunately none of them are local and other than VHT, I haven't been able to find a product in Canada to do it myself.
So unless somebody speaks up with a glowing recommendation for VHT, then I'll resign myself to shipping them away to have someone do it for me.
