Yeah, ceramics would be best, but it doesn't pay to have ceramic coated exhaust manifolds if I can't afford to buy tires for the truck.
This paint I used seems to be ceramic powder in an epoxy base and there are epoxys that will take the temp.
What I ended up doing was wrapping my exhaust manifold with exhaust wrap as well as a ceramic insulation. I insulated both turbos with turbo blankets. My top turbo is only 2" from my hood, so without the blanket it would burn the paint Lol.
Started the body work today. I was going to scab a roof from another smaller compressor, but decided to make a new one from a fresh sheet. I hate burning paint anyway, so nice to work with fresh material.
