I seem to recall some conversations many Many MANY moons
back about monel rivets used on firewall assemblies. Wasn't
my area of interest at the time. It would be interesting to
dig out a Cessna Service Parts catalog of the 1960's and see
what attaching parts are called out for oowl attach brackets.

I've got one of these critters on order. They're back-ordered
for about 10 days. Must be a popular item. Here's the manufacturer's
data sheet
http://www.aeroelectric.com/Mfgr_Data/Lamps/JKL_Lamps/ZLP-MULTI.pdf
The item stocked by Jameco is 3.5" long by .48" wide and
draws 350 ma at it's rated 10.2 volts. It's also said to
have a max operating voltage of 12 volts. 3.5 watts
dissipated into this area and volume suggests it's a POWER
device with no particular power conditioning capabilities
built in. I.e. it would best be driven by a constant-current
power source (like the buck-pucks).
Will know more about it when we can get our hands on one.

Yes, Bob, that is the answer. Our Sportsman kit came with a supply of Monel
rivets for the thin, stainless firewall.

Yet there are many thousands of RV-x's flying with regular A/N aluminum
rivets holding stainless firewalls to aluminum *and steel* structure.
Many of them for several decades.
Aluminum is primed; steel is either primed or powder coated (depending
on the age of the kit). Things get bent or cracked occasionally, but
I've never seen anyone on any of the user groups complain about rivet or
aluminum corrosion in the firewall area.

No, don't remember that. Ours were -3s and yes, and even then they were not
easy to drive. Two of us did it holding the firewall horizontal over a
bucking bar clamped in a vise.

With primer barriers, particularly on the aluminum. Most sheet stock in
use on kitplanes is alclad and doesn't generally need primer. All
extruded angle and bar stock is not clad and needs to be primed to
prevent corrosion. Many folks prime all faying surfaces (where two
pieces fit together) and it should certainly be done at dissimilar metal
joints.
