You can wrap the foam in a few things as a resist - used cling film before too. Parcel tape worked ok for me as long as you take the time to put it on without wrinkling.
Whether it needs vac bagging or not is really down to material choice and shape, e.g if you want to do carbon you will need to vac bag and infusion
At McLaren the vast majority of tooling they make for composite parts are machined from a really high density foam (but split moulds as apposed to a "lost" former)
