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.
Someone with an RV-7 had
a self adhesive, reflective type sheet stuck on the inside of his cowl. I
didn't look too closely at it, but he said he got it from Van's. I
used the .002 321 SS foil that McMaster Carr sells on the last version of the
lower cowl, and it worked fine, except where the exhaust pipe is within about a
half inch of the fiberglass. On that spot, it burned the cowl through the
foil. I ended up using a thicker (about .018 304 SS sheet over that small
area, but rather than gluing it to the cowl, I used pop rivets, with a washer
between the sheet and the cowl at each rivet. That gave it an air gap
underneath, so the heat didn't get transferred to the cowl. Worked
great.
This time, I just
skipped the SS foil, and used a larger piece of the .018 SS sheet, and spaced it
1/8" from the cowl. I'm confident this will work well, if I ever get to
try it.
I've spent the last
several hours with a wet vac trying to keep the water out of our
house. The garage had a couple inches when we noticed it, and
the water was just coming in under the front door of the house. Living
room carpet and baseboards are wet, also one bath room and two closets.
There was a foot of water in my front yard! I've been in this house for 13
years, and never has the water come up like this before last week. The
garage has been flooded now twice in two weeks. Sure hope my TIG welder
survived.

year flood plane, minus the flood insurance)
