I just ordered some, so I don't know. I still plan on doing regular sink lanolizing because I don't think the spray can soak into ever fiber the way the sink job does, but I plained on using it if I just needed a booster, or to do a REALLY good job at lanolizing by spraying it o afterwards. But who knows, maybe that's all I'll need. I'll have experiment. I'd be interested to see if anyone else has experience with this.
