Review: Works as advertised.... - I use this on highly exposed parts on my RV. I primarily use this for prevention in areas prone to rust. The best prevention is to ensure any rust is removed and painted appropriately. That being said, there are simply places that cannot be painted, such as scissor stabilizers or areas exposed to road debris. This is where this product comes into play for me. In one situation, simply because I did not have the time to properly fix it, I just sprayed it on the affected area to prevent further rust. By the time I got back to it, the rust was almost entirely removed. Because it was more of an unsightly issue than a critical component, I let it sit longer. After two weeks, it just about removed all the visible rust and protected the part even in dusty and arid conditions. It didn't seem like it dried out. I was impressed. This will be used for removal, prevention, and quick fix to prevent further damage until it can be properly fixed. Overall, this is a good product, but a bit pricey. Time will tell how much a 6.5 ounce can will last, which will ultimately determine its overall value. For effectiveness, it works great. I would recommend.
Review: Salty environment corrosion inhibition. - Worked great on AC coils etc. Seems to have stopped corrosion in salty environment. Going to put cleaning and WD 40 corrosion inhibitor application on a 6 mo schedule.

## 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.
