I have had most of the engine bay plumbing coated with aluminized ceramic material that is used on headers. Both Panteras now have at least combined twenty years and roughly at least three engine out/in procedures. The aluminized ceramic seems to be impervious to rust and maintenance free. IIRC, it is supposed to be bound to the surface to the tune of 10000 psi. Just like headers they easily coat the inside and outside. Do it once and forget it. Probably your nearest Jet Hot could advise you on pricing. My numbers are 10-15 years ago.
