## 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.

### ⭐⭐⭐⭐⭐ Must do maintenance for Garage door springs
*by K***N on August 7, 2026*

I've been using this WD-40 Specialist Corrosion Inhibitor on my garage door springs, and it's one of those maintenance products that pays for itself many times over. If you have a garage door, I honestly think this is a must-have. A light coat helps protect the springs from rust and corrosion, especially if you live in a humid or coastal area. Keeping the springs protected can help prolong their lifespan and delay what can easily become a $500–$700 garage spring replacement. Spending a few minutes once or twice a year is well worth it. The best part is how long a single can lasts. You only need a small amount each application, so one can can easily last for years for the average homeowner. It's inexpensive insurance for one of the hardest-working parts of your garage door. Highly recommended if you want to stay ahead of rust and keep your garage door operating smoothly for as long as possible.
