Don't let this happen to you...

I bought some new cold weather gloves today, JR Nitrogen. Very good in cold weather, I tried them out today in 18F and they were warm. However, it was raining/snowing a bit and my helmet visor got wet, so I used the thumb strip on the gloves to wipe them off. I get home and find out that my silverizer visor has marks all across the front that won't come off!!!

I checked the helmet documents and the glove tags...it doesn't warn of this anywhere. So, if you have a mirrored helmet visor, think twice before using the thumb wiper!!
