## Questions & Answers

**Q: Has anyone used this long term on painted surfaces?  Does it damage the paint?**
A: I have neither seen or read of damage to firearm surfaces caused by this product. These surfaces do not have traditional paint as a coating. That is my only application of this product.

**Q: If a spark or open flame were to touch an applicated area, would that ignite the lubricant?**
A: Let me check, if I am not back in 5 min... then yes.
