just got these parts back. they were coated by Baxter Custom Engineering out of florida. mason baxter is the only one in america that uses stainless steel in his coatings and it enables him to get a very high luster compared with jet hot or hpc which use aluminum in thier coatings. mind you, jet hot and hpc both have a great product, but baxter does the same thing with more shine. if you're thinking about chrome remember that any of the previously mentioned products once coated maintain thier finish with little to no maintenance, won't rust, and keeps the heat in or out depending on the use.
