Hi, Ira -
There was no barrier material other than minimal paint originally used
between the fender flanges, the shroud flanges, and the beading.  This
arrangement is a galvanic cell, and in the days when the cars were just cars
and lived outside and in the rain most of the time, corrosion was promoted
that dissolved the aluminum flanges.
Most Healeys see a much more benign environment today, but can still corrode
if exposes to enough moisture.  I just used a good coat of anti-corrosion
primer (called "Corroless" then, but Eastwood has something similar called
"Rust Encapsulator") on all the flanges before I reassembled the parts.
Since then (the late '80s) I have had only one rear fender off the car about
13 years later and there was no corrosion of the flanges.
A good coating of a good paint should be all you need.

Howdy oh wise ones....
I have removed all four fenders on my resto project. I ordered new fender
bolt kits and new fender beading.
I have always been of a mind that there was some type of material to isolate
between the bi-metal situation or actually tri-metal situation of steel
fenders, tin bead clips and aluminum body panels. There does not appear to
be any on my car when we pulled the fenders off. . It just seems like one
big battery to me.....
So should I use something or not?If so what?  I see material available, but
none of the various companies I have contacted about quotes for parts have
mentioned that I should use it.

Thanks again in advance..
