I have used Fibre Fax from Aircraft Spruce, just contact cemented to cowl, you can have exhaust pipes about 1" away and will not blister cowl, used it for 5 years now, I have even wrapped coolant lines with it that were mighty close to exhaust.

Subject: [FlyRotary] Aluminum foil for heat shield

I found that taking RTV and thinning it a bit with MEK I can "paint" it on the fiberglass of the cowl and then lay thick aluminum foil over it. It sticks very well and the aluminum is more than enough to handle any radiant heat. Now if your header is only an inch from your fiberglass then stainless foil would probably be a better bet.

I use Stainless Steel Shim Stock from MSC. They come in a tube 6" wide by 50" in all kinds
if thicknesses.

McMaster Carr also sells stainless "foil". I just bought some 321 ss foil that's .002", and plan to use that to cover some parts of the cowl.
