i am thinking of trying some of the cerakote coatings like transfer cote,high heat air cure,and insulkote.Iwas wondering if anyone has hands on experience with them and their opinion,tips,suggestions,thanks John

 

What are you coating?

 

i would like to coat the radiator and intercooler with transferkote,the manifolds inside with the insulkote,and the downpipes with arctic black air cure

 

have you used any of them?

 

I have used spray on wheel liner, does that count?
I thought intrakote is basically like thermal paste?

Doubt you'll find anyone who'd sign off on spraying stuff inside manifolds.
Samething with spraying rad with anything, it will just get clogged up.

 

Actually...

After heavily blasting the exhaust manifolds inside and out... and properly pre-treating them would make excellent substrate for a cerakote bond. The result would be a rust proof surface with favorably enhanced thermal tolerance. Akin to being polished, the inside surfaces coated will provide a less restrictive conduit for hot gasses to pass. The .1-.2mil application thickness might be construed as a surface area reducer, but the thermal improvements coupled with the smoother surface finish more than compensate the loss.

Fellows with ceramic coated up pipes claim better egt's and faster spool times somehow associated with keeping that heat in the pipes. It only stands to reason the more control you can place on that heat near the source... the better.

I will follow your endeavors closely John. To me it seems like a very logical and proactive bit of wizardry.

Never mind the naysayers... keep up the good work!

 

If it's strictly for rust, do the outsides of the manifolds. These don't seem to rot at all from the inside out, but they do rot from the outside in. Additionally, I agree with everything Chris said.

 

I would like to see this! If you decide to do this project please post pics.

 

I've done my up pipes silver and the 38r black, as well as rotors and some other non truck related things. Everything is still rust free. Theres pics in my album.

you used cerakote on them?

 

Could be, and some others. Some are air dry, some heat cure only, but do the same thing. One I used makes coatings for the military, not sure of the brand, but I spray them on with a small touch up gun. Even most air dry types can be heat cured so you can work with the part faster. I could find out from my source if you want. I usually get it in small unmarked cans of 4-8 ounces, but it will be a day or two.
