I asked a well-known specialty auto parts store in Phoenix where to take my tube headers to be coated and they responded that "there was only ONE place they would recommend, and that was APC on Fillmore St. in Phoenix". I backed that up with one of my engine and car builder friends recommendation as well. So, I gave them a try. They were prompt with a price in an email back to me, told me it would be "about a week" and sure enough in exactly a week I got a call saying the parts were ready. I held my breath when I picked them up, but they looked so good I couldn't believe it. AND, the price was exactly what they quoted me to the penny. Friendly and prompt with a great product....now I have a new go-to place for anything I want coated. Thanks again guys. NICE job. And, at a great price as well. FIVE STARS.
