Xtream Temperture Coating on Cast Iron Heads

[silverbullet07]

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.

We developed the XTC in Pontiac Metallic Blue for people just like you.

Yes, wire wheel and then sand with abrasive pad or paper (60-80 grit). Wash surface well with KBS Klean at a 10:1 (10 Parts Hot Water and 1 Part KBS Klean) ratio, rinse and let dry thoroughly. Apply the XTC in thin coats and at least 2 coats. If you are concerned about rust protection, apply 2 thin coats of XTC Primer before the XTC.

Please be sure to read carefully the XTC Directions and let us know if you have any additional questions.

Thanks for the information. Is it ok to wait 24 hrs between coatings or should I make sure I have a day where I can wait 8 hours for the 2nd coat?

[KBS Coatings]

Yes, you can wait 24 hours between coats. As a general rule, we always suggest within 7 days.

Guidelines:
For XTC aerosol, at least 30 minutes between coats and before temperature cure.
For XTC non-aerosol, at least 8 hours between coats and before temperature cure.

Please let us know if you have any additional questions.

Thought I would update and let you know I got the exhaust ports painted. The paint shade is a little different from my other Pontiac Blue Metalic however I think  the color will work with it. I have gone through the curing process. I let it idle for about 40 min. The center port got up to 450 +-  the other ports get about 350 +- at idle. 

It want been driven for another week to see the full potential of your paint generally the paint cooks of after the first ride so I'll update again. 

That i I would add a before after photo.
