Technical Rust neutralizer and glass

Loc***e makes a spray on rust neutralizer. Has anyone ever overstayed onto gl***? Is there any I'll effects?

 

The best rust neutralizer was when I moved from Ohio to Nevada....LOL...

 

Masking tape is cheap.

 

I did a little experiment and found that there's no damage to the gl*** from my investigation. Hope this helps someone out if they ever wonder.

 

Why not just mask it off prior to spraying the ****?
