Back on 1-3-01 I submitted a report on a heat shielding experiement I was trying.It was in the news letter and on the web sightunder tips & Hints.The test was to coat the right exhaust gasket manifold heat blocking flange with a painted on ceramic[called slip]to a 1/8 to 1/4 inch thickness As this took several coats it was nessesarry to let the material air dry some between coats.I also painted the right side of the right rocker arm cover[over the paint]with the ceramic.The heat from the exhaust manifold was suffecient to bake the clay to a solid ,yet porous state. The painted gasket flange became a
solid ceramic .Being an off white in color , it reflects heat as well as deflecting it from the rocker arm cover.The material painted on the rocker arm cover over the paint also bonded, providing additional heat protection.SURPRISE, [I thought it might just flake off the painted surface]Both ceramic coatings are alive and well after at least 15000 miles .Bob Chaney #2626
Hi Bob I think your experament is great where did you find the slip I'v looked here in Modesto and can't find anyone who has it

Hello Jim. Ceramic clay in the solid[pliable] form , or in the thick but pourable liquid form called "slip" can be found in ceramics stores,or in craft stores. I personally have only dealt with ceramic and porcelian types.Either will work. I used the porclian clay as it is what I had on hand from another project.You can make your own "slip" by diluting the clay to a liquid state with water.Thats what I did .The heat from the manifold will cook either clay to a porous solid state, which is an excellent insulator.But it is not hot enough to heat the ceramic clay to a solid non porous state,[2000+degrees].Have fun Bob Chaney
