My reading suggests that a metre of highly-hydrogenized armour (call it Wood or Ice in Spaceships terms; maybe something like pykrete) is a handy way to turn the neutral ISM atoms into separated protons and electrons, and my back-of-the-envelope-figuring from SS5p40 suggests it won't ablate too much from dust on the time-scales I'm interested in.
