Jet Hot Manifolds

[Unreal]

I picked up some pristine 178/879 manifolds a few years ago, and had them Jet Hot Coated. I have never liked the look...more like Battleship Gray thas fresh cast iron. I've got the motor out to replace a wiped cam, and the damage it caused, and was considering having MacNeish do his magic stainless coating on them. The old ceramic coating has to come off, but Jerry said he doesn't have the right equipment to do it. I'm not sure what the right equipment is, so I called Jet Hot....they weren't sure either, but the sales tech said they soak stuff in nitric acid before coating. Of course I don't have a nitric acid vat.

Anyone have any experience with removing ceramic coatings, or have any ideas on how to proceed? Or should I look for another set of manifolds and have MacNeish do them, instead of trying to remove the ceramic coating?
