Yes, my bad. I had SOS on the brain when I saw scotch bright.

Are you sure that you didn't use some other product?  I'm not aware of any
iron in Scotch Brite pads and I have recycled a lot of aluminum using the
product with no issues.  3M claims it will never rust:

Scotchbrite came back and bit me some years ago. The "metal in it" got in
the pits of elements and actually made the antenna look like it rusted a
month later. Even though it wasn't the aluminum, it was the metal in the
pad. They make brass pads too.

I had to take it down, use 400 grit to get it out and then clear coated it
and it's been up for some time now. It stops it from deteriorating when you
live 900 ft. from the ocean when it's covered with something. I have some
that have been up 7 to 8 years and that's a good bit next to the sea salt.
