I have also heard this about VHT's hi temp ceramic paint, but never tried it. I have used it on the OUTSIDE of a pipe I welded, and it worked great FOLLOWING the instructions closely. They got a whole curing technique.
Bluing is the cause of two things mainly the fuel mixture... the other is hand prints... however, my V&H pro pipe has discolored to a gold after the collector. My mixture is right, but I've seen others that are very blue. |
