Safety warning stickers on visors
This is probably a silly posting, however, I'll do it at the risk of ridicule. I've never been accused as being the egg in the dozen.
Anyway, for whatever reason, I have believed these warnings on the visors were silk screened on and were not removable. I've always thought they were pretty dumb and annoying.
If you take a hair dryer to them and peel off while heating as you go, they come right off with no residue at all. It only took me 10 months of ownership to figure this one out. It provides a cleaners more professional inside look.
I hopes this helps someone else who had not thought about removing them in the past.
