McMaster Carr sells various thicknesses of thin stainless steel. I used some .005" for some of the "NACA duct" protection from exhaust heat that I put under those ducts. See http://www.mcmaster.com/#catalog/117/3710/=bh9nfp . A 24" x 50" piece of .005" is $42.05. Also, a 2'x3' piece of Fiberfrax can be bought for $30 from http://www.aircraftspruce.com/catalog/appages/fiberfrax.php . I used high temp silicone to hold the Fiberfrax/stainless in place until my engine mount and cowling fasteners were in place. My guess is this setup will do the job, although I have not tested it in flight, fortunately.
I flew late yesterday for a little while, thanks to the longer days offered by daylight savings time (which should be a year-round thing, as far as I'm concerned). I did eight touch-n-goes at four airports in a matter of maybe 45 minutes, and ended it with some nice sunset pictures...
