Guys, I've used Commercial ceramic coating for three years. The stuff sucks as far as I'm concerned. Three occasions I've had them redone on the RFGT40 and they looked totally like sh!t after three months.
Now I use VHT header paint. It looks really great and it's a heck of a lot easier to touch up.
Plasti-cote also makes a good product.
