Chris, I replied to your ques the othe night and when I hit submit, it all got blown away. First of all I do not use a primer with the High Heat paints because the primer may not stand up to the heat and cause the color paint to chip off.
As far as prepping, I just use what ever is appropriate to get the metal perfectly clean and make sure all residue or film is removed. There are many parts/areas that I like to bead blast because it does an excellent job of etching and cleaning the surface and the paint adheres very well. I always paint my Chev engines with 2107 which is not as orange as Chev engine orange, but it is extremely durable. In the past for under hood black, I have always used 1614 High Heat black, but as you can see L89 says the 1613 is a better match to factory. So I will give it a try. I always like to learn new ways and new products.
L89,
How is the resistance to heat and the elements with 1613?
