I've seen those 1500 degree Hi-temp paint for header and stuff at pep boys, and was wondering if these paint is worth it or they will just peel of. wanting to paint my cast iron manifold with it cause my manifold get pretty damn hot.

 

i would recomment 1800 degree paint.

 

On cast iron parts I have always used POR-20 and have always loved it. The most important thing is to clean the parts perfectly. Restomotive laboratories, the company that makes POR-15 and POR-20, also makes a great product called Metal-Ready that prepares metal right by cleaning off everything and leaving a thin zinc coating.

 

Do you have a link to the site for the POR stuff?
