Charlie,
Agreed on the explainin'. FWIW Jet -hot does make those claims. I can tell you from personal experience that it does work. Yes you must send your parts to them to get them coated. It is a baked on process like powder coating, but with a ceramic base. The best results ARE when doing tubes inside and out. I even found that I picked up just a bit of power on the dyno after the process.
