Does anyone have a coating company they are using that they are happy with?
Specifically heat barrier coatings for the bottom of an intake manifold. Here is who I am looking at currently.

Thanks for any recommendations,

 

Personally, I doubt you'll notice much heat reduction on the underside of an intake manifold.

I had some exposure to Perkin-Elmer Magnesium/Zirconate ceramic coating of jet engine parts. I always wondered about coating a set of pistons tops and possibly combustion chambers, but never did it.
The main reason those parts were coated was to prevent erosion of the "burner cans" and combustion chambers.

 

Likely any aerospace coating biz can do them, smaller ones more likely. I always had intakes done when not using turkey tray. Worth it? Not worth it? I don’t really know but $40-60 to coat each over the years, it made me feel good.

I would be sure it’s clean and I used to mask mine. Makes it easy for them and eliminates risk of coating the whole thing if there is a communication breakdown. Even if they want to sandblast it, I wouldn’t think masking it is a waste, they can just add a strip of tape before or after the blast.

 

Thank you both for the input.

 

A little late but, I've used their coatings on a couple turbine housings and it worked very well under extreme conditions.
