A couple of big patches of Tegaderm are indispensable. It's basically stick-on replacement skin. Classic use is to cover up road rash, which it's fabulous for. I've also used it to treat saddle sores/chafing (it's great for that, slick on the outside and breathable) as well as blisters. You can leave it on for days at a time and it makes it so wounds don't scab over and crack, stick to bandages, or rub on clothing. Wonderful stuff.
