It's better to have two hands than one glove.
I would coat them with Clear Shield.
Exactly so. But before coating them I'd break out my mega collection of Sharpies, every color know to man and kept on hand just for touching up the odd zits on banners and vinyl, and have a go at repairing what I could. The trick with Sharpies on banners is to dab lightly, not stroke. Then coat them with Clear Shield which not only will protect them from further violence, but will tend to maks your touch-up efforts as well.
