Road rash has ROAD in it, so no - you wouldn't want to wrap that in your skin.
2 of my last 3 tattooists swear by the wrapping method. They say it keeps the dirt out and "keeps the body's own natural headling juices in". You've got to give it about 4 half hour drying periods each day after washing and before re-wrapping - but it does eliminate any scabbing and hastens the initial healing process. I'm usually pealing by the 4th day and then no more wrapping. This process would be a pain in the butt if your work schedule might interfeer with the mid-day washing, drying and re-wrapping.
