Remove those FUGLY warning labels.
I did this mod a while ago, FWIW here's the details.
I know others have been successful with goof-off; but I didn't want to get into that mess.
With the Bimmer the label is fused directly onto the vinyl (or extended leather)
Sooo I gave it a try with a hair dyer a scraper & a few prayers.
Use the dyer on high and it will separate from the visor with the scraper.
It's easiest to remove the visors from the car (2 screws)
& screw them down to anchor them during the operation.
The process...
& the results
There was a little residue after removal.......
Isopropyl & a microfiber cleaned that up.
I followed that with some 303 to condition the vinyl.
It is soooooo nice to be rid of those labels.
