## Questions & Answers

**Q: Can this be used alongside a pre cut paper gasket?**
A: That's how I used it. Placed a thin film on metal surface to fill in scratches and a thin coat on the paper gasket and all is well.

**Q: Is this a good thread sealer on a pipe fitting on and aluminum water pump?**
A: Yes but let it cure overnight for best results. If you don't have the time make sure everything is dry and at least let it sit for a few hours without getting wet.

**Q: Safe for potable water like in dishwasher?**
A: No. PermaTex states it is not safe. Look for a food grade sealant

**Q: Hi good morning, I would like to know how long until you ship the item out?**
A: Not sure
