Very high temp paint???

has amyone tried this? http://www.por15.com/High-Temperature-Paints/products/8/

the directions say paint it on, let it dry to the touch and then heat it up to over 300 degrees to fully cure it. then it will withstand 1200-1400 degrees. thats what i plan on using on my build when i get to that point.

I used it (applied it just as the directions said) on my headers but didn't have a way to cure it (no oven). I thought maybe I could install the headers and fire it up for a little at a time keeping an eye on the temp with a digital temp gun making sure to not go over 300 degrees. Problem was it scratched off so easy I had half of it scratched off installing the headers. I went ahead and fired it up and within seconds it was peeling off. I've used POR-15 chassis paint with great success but the header paint didn't work good at all for me.
