Well, tell your friend he/she can have the best of both world, protection of Klasse and the look of carnauba with a topper of carnauba. I recommend either Blitz or Souveran as the carnauba topper.
Locally try Meguiars #26, I never had it stain trim for me, but I never had it touch trim. I apply it with care to avoid the trim. I got my #26 at an autozone (1999.) You van always look into bodyshops and NAPA for the mirror glaze and pro line of Meguiars, they might carry it.
Mask off the trim with tape?
Other than that, can't really help much.
