Can you still buy aluminum siding?

Reattaching aluminum siding corner post?

• During a storm, I had a 10-foot corner post come off of our aluminum siding. It looks like it had just been duct-taped at the top, and it's a bit of a mystery how it could have originally come out. In any case, it was incredibly difficult to find someone who wanted to find a solution that didn't include taking off a lot of siding -- compounded by being such a relatively small job. Finally, yesterday, I convinced a siding guy to spend an hour forcing it back into place, then caulking it at the top. He added that it could come out again, however, so he strongly recommended securing it by nailing right through the siding at an angle, hopefully catching the inside of the corner. (Apologies for not knowing the terminology.) Given that this is a makeshift solution, does this sound right, and are there any issues to consider when it comes to which nails to use, etc.? Many thanks-

  It is unfathomable to me why this "siding guy" didn't nail the damned thing himself. I generally use screws when working around things like this, as one slip off the nail head and the hammer will leave a nice big dent in the aluminum. Also, you can get hex head galvanized screws that have rubber washers under the head. That way water won't leak past the fasteners and get behind the siding.
