Regarding ways to minimise paint wear from handling on high end toys, I usually wash my hands with soap and water before handling my toys to remove any sweat, oil, grease, food etc.
I also tend to hold my toys on unpainted areas, as much as practicable.
So far this seems to work for me.
Of course it doesn't prevent mechanical wear, i.e. where you have parts of the toy rubbing against each other.
