exaust manifold paint

OK I found the web site. Did you guys purchase the kit or just the exaust manifold paint, it looks like you brush it on let sit for 24 hrs and put another coat on. It also talks about heating to 400 degrees before applying second coat, is that how you guys did it and did you use and oven to reach the 400 degrees.
I know its alot of questions but I dont want to spend alot of money on this stuff and have it not work correctly. Thanks in advance Tony :salut:
