Hi, Corey, Since the D5 evaporates, it does not stick around to harm the tape. I have looked at one or two tapes I've treated with it a year or so after the treatment and there was no ill effect. As some idea of how it evaporates, I over-lubricated a cassette the first time I tried it and the Dragon stopped working. Two weeks later the Dragon's health was back and working fine. I have tried open-dish evaporation tests and it seems to disappear completely. It's not that much of a mystery chemical. I suspect you use it frequently in personal care items. It's what provides the slipperyness in many shampoos and other such items.
