dimpling

Whatcha need to do is take a little scrap of aluminum with the correct
size hole in it. When you put the cleco through your part, you put the
scap on the end of the cleco and that will "clamp" the parts to your cleco.

Doesn't help if he's closing a part or has a bunch of holes that need
clecos. If he really needs to do as you suggest washers are cheap and
smaller than you the scrap you suggest. I can't imagine a situation
where one would need to use a back up if one is using proper proceedure
and good tools.

Using the scrap backup is an accepted practice for holes that have been
dimpled, but are too big to hold the correct cleco due to the deforming
of the hole from dimpled. If its something that needs a blind rivet,
then of course, this won't work.
