I am leaning towards Jet Hot again Torch.
I had my last set of TA headers coated by them.
They were used, a couple of years old( bought new by me) when I had them Jet Hot Coated.
It looks like the coatings have improved.
A few others I have checked out.
There were many more companies prior but I think the Great Recession of 2008 -present did them in.
Jet Hot survived.
Google search does not show all.
You have to click on Jet Hots website & look around.
