We have got a material that is a ceramic paper that is 1/8" thick that can be glued to or bonded in the fiberglass. I put it on an oven element and held my hand 1/2" over the 1300f element. It is not cheap, but it really works. There are some things you need to know about coatings. The surface temp IS reduced over 200f, get a infrared thermometer and try it yourself. The radiated heat is greatly reduced with coatings. The reason black is a better insulator is because the bright coatings all have aluminum in them and aluminum radiates heat better than the black pigments. Also,reguarding header wraps,unlees you like to buy headers, dont't use them. Talk with any header mfg. and they will tell you that it will void the warranty! This is not because they want to coat your headers, but it is because the extreme heat retention will burn the carbon out of your headers and eventually blow a hole in them! When you take the wrap off the header, in addition to being rusty, after you blast them they will look like dried mud and they are ruined. IMCA mods, "dirt cars" will not make 1/2 season with wrap but will run over 3 seasons with coated headers. Pat
