What product did you use, and how long did it take for the rashes to heal? I had horrible gravel rashes last summer - they were so bad I feared some of the stones may have been lodged in my wounds. Luckily, that wasn't the case. Anyway, the seal-off treatment worked wonderfully - fastest healing possible, because the wound is kept moist by the plasma itself, and the fibroblasts can rebuild the tissues in a protected envirnoment. The classic patch/dressing method requires daily or even more frequent re-dressing, which just kills the fibroblasts.
