## Questions & Answers

**Q: Does it come with the plastic nozzle?**
A: No! I ordered 3 tubes and no nozzle. I wish I’d have known that before ordering.

**Q: Can you sand it?**
A: Thank you for your question. We like to know more details regarding your application. When sanding is involved this imposes possibility of exposed metal causing corrosion/rust.  Please contact us at 877-666-2277 option 2 to discuss your application.

**Q: What chemical can be used on it to “smooth” after applying?**
