[DeTomaso] Insulation material?

71 Pantera well worn 377 twin turbo motor. After a short trip yesterday I noticed one of my turbos was leaking oil. A small amount on the input (pressure) side. A quick tightening and it was fine. I did notice a small paint bubble on the deck directly above the turbo. There is about 2 inches clearance about the turbos but the deck was really hot to the touch. Question. I am looking for a product that can be applied (as a sheet or thin blanket) to the underside of the deck above the turbo. I have some chromed sheet metal shields that I may be able to fit to the turbos but would like the real protection of an insulator. Thanks in advance to the "collective", jerry knotts
