I normally turn off my heater when I prespray it down, but thanks for the reminderI would use 12 oz. per 5 qt HF container for light oiliness in traffic lanes (1.5 oz/gal. diluted for TM)
Remember that inline sprayers inject less, as the water temp approaches 200 degrees.
But it confuses me a bit because I've been told for a long time to use butyl based liquids on poly, and you're the first one to bring up a POG
Why? What makes a POG better than a butyl?
