KR> Firewall material

I am pretty sure that you can get thin galvanized at Home Depot.  Any
local sheet metal place should have it also.  I got a 4' X 8' sheet of I
think .016" when I redid my Sonerai and Starduster firewalls.  I think
it was something like $30.  Aluminum will not block a fuel fire for very
long.  All aluminum planes have stainless or galvanized firewalls.  And
now that I look, Spruce sells a 3' X 2' piece of .016 stainless for only
$35.
