No, you MUST add the anti-oxidant for aluminum, go to home Depot or some
such place and get a small tube of it. first clean up the wire end with
light sand paper (make it shiny and clean) then coat it with the
anti-oxidant and then assemble it into the new terminal connector.

Better yet, put the anti-oxidant on the wire *first*, then clean it
with the sandpaper. (Or apply a blob of anti-oxidant to the sandpaper
first). If you sand the aluminum dry, it starts developing a new oxide
coating instantly wherever it is in contact with oxygen. If you put
the anti-oxidant on first, enough to keep the aluminum surface wet,
then oxygen is excluded and the aluminum surface doesn't develop an
oxide layer.

Yes, the sandpaper will get covered with anti-oxidant. Yes, it's
messy. But it's the right way to do it.
