The cowling on my Lancair 360 uses these and I absolutely love them, I’d like them on my next aerobatic plane, but not sure we’ll be able to make that happen.
My T-18 used them as well, in the ailerons and on the horizontal tail.
Edit: the aluminum variety. That link takes me back to years of EAA membership, and flying my T-18 to the annual Rockford flyin (before they moved to Oskosh)
