## Questions & Answers

**Q: I question whether 6 ounces is needed to lube the seal. It seems that pouring in just enough to completely cover the bottom of the bowl would lube it.**
A: I'm sorry to say this stuff was garbage. It was easier to just go buy a new seal than to waste the $ on this. Didn't even work a little bit.

**Q: do i pour in while the toilet has water in it or should the seal be dry?**
A: Pour in with no water. Make sure valve is closed. Pour about a 1/4 of container if I remember correctly and leave overnight. Fixed my seal. Hasn't leaked since

**Q: Can it be used with valve lube or is this the same thing**
A: The two products are compatible with one another and serve two different purposes. Toilet seal works in the bowl to keep the flush valve functioning . Valve lube goes straight into the blackwater (poo) tank and ALSO in the greywater (sink&shower) tank to prevent problems with the seals that keep the drain valves operational. I use both as preventive maintenance.

**Q: Does this work for the seal on  cassette toilets?**
A: This is not a sealant.  It is simply advertised as a lubricant for sliding toilet parts.  If you're using it as such....it should work
