I used Goo Gone and the painted version came off easy.
I did not even remove the visor. Just put Goo Gone on a rag, lots, and held the rag to the warning. After about 30 seconds I pulled the rag back and looked. The warning was peeling off. Another 30 seconds of clean up with the soaked rag and the visor looks like nothing was ever there.

If you like the covering stickers great, but getting the warning off the visor is really not hard.

 

Anybody wonder just what "Nature" was removed in denatured alcohol?
Sorry, off-topic.

 

Yeah I work at the dealership and I noticed that when sitting in a convertible the other day... Your mirrors are also incredibly small too! Kinda cute how small and discreet they are .

 

Haha! Yeah I've wondered that before too.

A quick google search turns up this from Wikipedia:

"As used in the phrase denatured alcohol, denatured means "a specific property of ethanol, its usefulness as a beverage, is removed". The ethanol molecule is not denatured in the sense that its chemical structure is altered."

Hmmmmmm. So they add something to make it undrinkable. Hmm. Don't confuse it with your normal alcohol
