First, I guess you are aware that posting the same topic in multiple forums is against the boards rules, if not reread the rules you agreed to when signing up.
Second, if you plan on moving/handling the figure a lot a bit of lost snow will be your least worry. Worry more about things breaking off, paint rubbing off, and so on.
Most figure modelers I know only semi-finish the figure and leave the final assembly till they are at the show/contest. And most of the figs get some form of damage on the way home.
If you plan on moving your figs/kits a lot you need to plan those steps prior to staring the fig/kit.
I.e. does the figure need to be removable from the base, how is it going to be shipped, which parts can easily break off, can I make those easily damageable parts removeable, etc.
I learned the hard way and spend many an hour at the setup table doing last minute fixes and repairs with too little resources and materials.
IMO and IME there is a big difference between building for yourself and building for a Show/Event/Contest.
FYI, the figs I take to shows and events on average cost between $150~300.
