I have a set of Heads on a Pontiac 400 motor that engine paint does not stay on the exhaust ports. I purchased some of your Pontiac Metallic Blue to try on them. I plan to Wire brush the exhaust pots well and clean with your KBS klean. Then foam brush a couple light coats of the Extream temp coating.
Is there any thing else I should do. If this works and looks good, I will spread the news to the Pontiac community.
