I found some stuff in an auto speed shop that has AL bonded to some sort of fiber insulation with tar looking adhesive (protected by peel-off wax paper) in big sheets that I just cut to size, peel and press onto the cowl. Works great. I was baking the paint off the cowl around the exhaust, but no more. If anyone wants, I'll try and get a brand name, etc. ... Jim S.

Bob, I use MEK mixing the RTV and MEK in a cat metal food can and then
brushing it onto the cowling. Acetone might work as well, just haven't
tired it. You don't want it watery, just thinned down enough to spread
easily with a brush (I use the plumbers throw away metal handle acid
brushes). Then lay your aluminum over the spread and press it down firmly.
I use grocery store heavy duty aluminum foil. You can tear the foil but it
stays attached and it keeps the heat and oil from the fiberglass. Its easy
and cheap enough to replace if you mess it up.
