I'm not sure what the best way to transport chocolate is, but what if you gathered two sets of your chocolates. Set 1. Finished chocolates with that 'showroom finish'.
Set 2. Finished, but unmolded chocolates to be unmolded when you arrive. Leaving the chocolates in the molds will keep them from bumping and getting fingerprinted.
Having the two sets should allow you to select from the best of either.
Thanks,
