Good thread. My 2 cents: Be sure to specify and buy Alclad 2024. All aircraft 2000 series is supposed to be alclad, but you may still find non-clad 2024 sheet goods from surplus suppliers and local industrial suppliers. I made this mistake once. I replaced my front panel in the
Caravel years ago with 0.040 T-6 alclad because I had it left over from my airplane restoration days; it's a lot less likely to dent, but DO NOT try to form it.
Andy may have better feedback than mine because he gives warranties!.
