In terms of working with aircraft grade ALCLAD aluminium for the first time, I would suggest doing a little work on the boot cowl metal before getting stuck into the metalwork on the wings.
The alloy in the wings is decidedly structural. Mistakes are unacceptable and have to be corrected, which can be a big difficult job. The boot cowl uses smaller pieces of aluminium and they are non-structural and oversize, so they are the best place to learn new skills. Any serious mistakes can easily be repaired or replaced without drilling whole sheets off the wing structure.
