[Healeys] fender bead insulator

[I Erbs]

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..
